Elevator pitch

Immigrants are generally not evenly dispersed within hold countries; rather they tend to swarm in details neighborhoods. But does clustering in country enclaves help explain the persistent differences in employed rates and also earnings in between immigrants and the native population? Empirical research studies consistently find that resident in an enclave can increase earnings. While that is quiet ambiguous whether mostly low-skilled immigrants benefit, or even if it is employment probabilities space affected, it is clear that results are pushed by enclave “quality” (in regards to income, education, and employment rates) fairly than enclave size.

Key findings


Studies based upon refugee dispersal policies suggest that living in enclaves is associated with greater earnings.

Higher income are pushed principally through enclave high quality (rather than enclave size): immigrants benefit financially native high-quality enclaves, and in terms of employment opportunities.

There is some evidence that low-skilled immigrant may benefit most from living in enclaves.


There is no conclusive proof that the dimension of one enclave rises employment rates.

Enclaves might reduce the employment chances of highly-skilled immigrants.

Immigrants’ labor market success have the right to be decreased if the country networks in enclaves room of low quality.

Evidence is mixed on the size of time that takes because that enclave high quality to influence on immigrant earnings.

Reliable proof is mainly based upon policy experiments concerning asylum-seekers, while evidence on financial migrants is rare.

Author"s main message

Theoretically, the is far from clean whether ethnic clustering, or enclaves, boundaries the future of labor market integration the immigrants, or rather helps integrate immigrants an ext successfully into a new country, early to better access to information and also jobs. Empirical evidence, however, suggests that earnings may be greater for immigrant settling in country enclaves, depending mostly on the quality of the co-ethnic network in one enclave. Thus, policies that encourage immigrants to resolve in regions with reasonably high employed staff rates and education levels amongst co-nationals may advantage their integration right into the wider host-country job market.


The increase of immigrant populaces in most nations has led to rising concerns around the causes and results of immigrant concentration. Political decision-makers are an especially interested in the question of exactly how living in an ethnic enclave may affect immigrants’ labor market integration. In the broader public discourse, immigrant enclaves room often connected with a voluntary socio-economic isolation the immigrant groups from the mainstream society, and residential segregation is viewed as a hindrance come labor market integration. In fact, the are afraid of “ghettogimpppa.orgtion” is just one of the main disagreements for asylum-seeker dispersion policies applied in many Western countries.

Despite these widely-held beliefs, the true impacts of ethnic enclaves on immigrants’ labor market outcomes are far from obvious. Immigrant could as well profit from life in an enclave. Society networks in enclave neighborhoods can provide immigrants with beneficial information about job avenues and carry out shelter indigenous discrimination, both of which might be conducive to labor sector success.

In check out of raising migration movements approximately the world, and also in consideration of the truth that there are currently policies in place that promote spatial dispersion of just arrive refugees and also asylum-seekers in many countries, the is important to attend to the inquiry of whether living in an ethnic enclave impacts immigrants’ (asylum-seekers and economic migrants) labor market opportunities—and if so, whether that benefits or hinders their effective integration into the host-country labor market.

How can living in enclaves influence immigrants’ labor industry success?

The clustering of immigrants in ethnic enclaves can influence their labor sector prospects in numerous ways, and also the direction of the all at once effect is a priori unclear. Country enclaves may carry out a “warm embrace,” specifically for newly arrived immigrants, with the ethnic network in an enclave providing valuable information on avenues in the job market, job contacts or job-search networks <2>. Word-of-mouth via an individual contacts is often discovered to be more efficient in offering reliable info than formal channels. The is also possible that enclaves directly carry out jobs in ~ the so-called “enclave economy,” because ethnic company owners are likely to rental co-ethnic employees <3>. A sushi restaurant, because that example, may prefer a Japanese come a aboriginal applicant, which would create a form of optimistic discrimination that immigrants welcome in ~ an enclave economy. Furthermore, immigrant employees in one enclave economic climate avoid labor sector discrimination they may encounter outside the enclave. Overall, the benefits linked with life in one enclave can be assumed of together a “buffer,” i m sorry reduces the price of cultural or language assimilation by making these needs less necessary to labor industry success. Residence in an ethnic enclave may because of this benefit immigrants’ financial performance.

However, there are likewise reasons why country enclaves can hamper immigrants’ financial assimilation. First, an enclave economic climate can offer only a limited number that jobs. In addition, incomes in one enclave economy are frequently lower than what can be earned in the larger host-country labor market, whereby there is a greater variety of alternative job opportunities. Second, while a neighborhood enclave economy can offer job methods in the quick term, castle might come to be “mobility traps” in the lengthy term by reducing the incentives for immigrants to acquire crucial host-country skills, especially language skills. This would limit the avenues of finding or relocating to better-paying tasks in the broader labor market, possibly outside the enclave. Another argument because that adverse enclave effects relates come the observation that ethnic communities emerge due to discrimination in the housing market. Consequently, ethnic enclaves are usually located geographically much away indigenous the many attractive employed staff opportunities, which in turn hampers immigrants’ opportunities in the labor market.

Empirical studies are in the most component unable to test specifically any type of of the over mechanisms; rather they estimate net effects. Because the direction the this as whole effect is theoretically ambiguous, it need to be determined by empirical analysis.

The residential sorting problem

A major problem in examining potential effects of living in one ethnic ar is that immigrants space not randomly assigned to neighborhoods. Rather, residential place is an individual or household choice. That is because of this quite most likely that individuals select where to live based on individual an abilities that also influence their labor market outcomes. For example, if immigrant with fairly unfavorable job market an abilities locate in ethnic enclaves to a higher extent, and additionally experience more difficulty in finding jobs, one conclusion can be the there are an adverse associations between enclave residency and employment probabilities, solely due to such residential “sorting.” Those immigrants would certainly in all probability have obstacles in integrating right into the host country labor industry anyway, regardless of of whether they reside in one enclave or not. On the various other hand, highly-motivated immigrants could move the end of enclaves. Consequently, a naïve comparison of immigrants’ labor sector success, inside and outside enclaves, cannot determine whether life in one enclave actually reasons adverse labor industry outcomes. In sum, any type of empirical examine that do the efforts to carry out causal impacts of enclaves on immigrants’ economic performance must credibly attend to the “sorting problem” explained above. In fact, this is the key empirical challenge that needs to be addressed in the literature worrying enclave effects.

Several studies avoid the difficulty of sorting in ~ the community level by assessing variation in enclave size across larger geographical areas <2>, <4>. The underlying assumption is that the sorting problem is less prevalent across 보다 within cities (or regions). One more approach is to manipulate variation at the really disaggregate geography level of residential real estate blocks <5>. Here, the presumption is the lack of endogenous sorting at the block level within neighborhoods. Studies based upon these approaches discover that immigrant enclaves (or enclaves comprised of ethnic minorities) are, top top the whole, harmful come employment and earnings.

The “ideal” approach to studying enclave impacts that room not affected by the sorting difficulty would it is in to execute a policy experiment whereby immigrants space randomly distributed across neighborhoods, or regions, in a organize country. Policy experiments that come close come this setup are spatial dispersal plans that are exercised by part Western countries, wherein refugees and asylum-seekers are randomly assigned to locations upon come in the organize country. 4 empirical documents report causal approximates of the impact of ethnic clustering ~ above refugee and also asylum-seeker labor sector outcomes <6>, <7>, <8>, <9>. In order to discover causal effects, this studies exploit the quasi-experiment that refugee and asylum-seeker placement plans in Sweden, Denmark, and the US. In particular, they use the fact that refugees are distributed upon arrival across the respective host country by public authorities, i m sorry precludes castle from prompt self-sorting follow to their own preferences.

Studies based upon refugee and also asylum-seeker dispersal plans present, to date, the methodologically many rigorous proof of enclave impacts on immigrants’ labor industry integration, while similarly reliable evidence worrying economic migrants is really rare. Yet, back humanitarian migrate represents just a small part of as whole migration to OECD nations (Figure 1) and the evidence concerning asylum-seekers might not be strictly generalgimpppa.orgble to every immigrants, the still provides necessary information. The main reason because that this is the labor market integration is most likely to it is in slower and also less successful for asylum-seekers than for economic migrants, due to the fact that refugee migration is not urged by employed staff reasons. The effects discovered for refugees and also asylum-seekers might thus be seen as a “lower bound” of enclave impacts for various other migrant groups.


The researches on Sweden and also Denmark look at at procedures of refugees’ labor industry outcomes between six and eight years after assignment <6>, <7>, <8>. In ~ this point, individuals have themselves chosen where to live (after early stage placement through the dispersal plan asylum seekers are cost-free to move). Naïve approximates of associations between enclave size and labor industry success are therefore prone to the sorting problem described above. The researcher then account because that potential sorting right into enclaves by using details on every individual’s location of initial assignment under the dispersal policy. Due to the fact that the assignment was made decision by the general public authorities, this strategy exploits exogenous sport in enclave size that should not be regarded individuals’ own ar preferences. Such estimates suggest a causal relationship in between living in one enclave and also labor industry success, rather than just a correlation.

Interestingly, the comparison in between the naïve calculation of the enclave effect and the calculation that accounts for causation is informative about the extent and direction the residential sorting. The research studies on Sweden and Denmark provide clear evidence of “negative” residential sorting, in the feeling that immigrants with relatively unfavorable job market characteristics tend to locate in enclaves to a greater degree <6>, <7>, <8>. Hence, naïve approximates are downward-biased and also this bias seems to it is in severe. In fact, while life in an enclave shows up to be connected with income loss as soon as sorting is no taken right into account, revenue gains are found when managing for an adverse sorting right into enclaves.

Who wins and also who loses?

The research studies for Sweden <6> and also Denmark <7> that manipulate refugee and asylum-seeker placement plans to provide credible causal estimates find evidence that living in one enclave municipality is connected with considerable earnings gains. The examine on Sweden suggests that these positive effects exist largely for the team of low-skilled immigrants, vice versa, the high-skilled carry out not significantly benefit (but additionally do not lose) from life in one enclave, in terms of earnings. For immigrants with fewer 보다 ten years of schooling the authors uncover that boost in the enclave size (measured as the share of co-ethnic residents amongst the regional population) by one typical deviation is connected with one earnings acquire of approximately 13%, eight years after immigration. The research on Denmark likewise finds enclave size to be linked with revenue gains. Yet, this impact is found to amount to 18% in yearly earnings, 7 years after ~ immigration, irrespective of skill levels. This argues that, in comparison to the swedish study, over there is no clues of distinctions in the income return to life in an enclave throughout educational groups. Nobody of the studies finds far-reaching gender differences for the enclave size effect on earnings. Results of the Danish study additionally indicate that income increase with enclave size, but at a decreasing rate.

These 2 studies additionally investigate even if it is enclave residence influence immigrants’ employed staff rates. The research on Sweden reports zero results of enclave size on employed (i.e. The probability of having actually positive earnings). Similarly, the examine on Denmark find no significant association between enclave size and also employment rates for the team of low-educated immigrants. However, the team of highly-educated immigrant in Denmark appears to endure a to decrease in employment probability of around 2.1 percent points for every conventional deviation boost in enclave size.

Overall, there are indications the at about seven or eight years after immigration, low-skilled immigrants experience stronger returns to living in an ethnic enclave 보다 the highly-skilled <6>, <7>. This is in line through the finding the lower-educated immigrants have a relatively stronger propensity to resolve in enclave communities.

It’s enclave quality, no size!

The enclave literary works points come the prestige of the quality of the ethnic network that immigrants room exposed come in enclaves. In fact, empirical studies present that high-quality enclaves, in terms of income, education, or (self-)employment rates, show up to journey the confident earnings effects <6>, <7>, <8>. Hence, residing in a fairly low-quality enclave may actually harm labor market outcomes.

By explicitly experimentation whether there is an independent result of enclave size independent that enclave quality, a 2nd Danish study, again using the refugee dispersal policy, finds that this is not the case <8>. In fact, when managing for enclave quality, the impact of enclave size is negligible, both for employment and also earnings. ~ above the various other hand, the effect of enclave top quality (measured as the neighborhood co-ethnic employed staff rate) is positive and statistically significant. Overall, this results indicate that whether the influence of ethnic enclaves is optimistic or an unfavorable depends top top the quality of the country network in the enclave.

A examine on immigrants in the united state finds that the result of enclave size on both earnings and inactivity varies with the average education levels of ethnic teams <10>. While teams with very low education levels, such together immigrants indigenous Mexico and main America, suffer an unfavorable consequences from life in enclave communities, groups with reasonably high education levels benefit. The results additional indicate the the turning point of an unfavorable to positive enclave effects is at about a group’s average education and learning levels, i beg your pardon is in between tenth grade and also minimal post-secondary education. Thus, living in an enclave where most co-ethnics have post-secondary degrees is beneficial, while life in one enclave where many adults have actually education below tenth grade, shows up to it is in disadvantageous.

Another research on the UK finds that living in near proximity, i.e. Within one hour’s take trip time, come a huge number that employed neighbors of the exact same ethnicity is positively linked with job-finding rates <11>. Interestingly, this effect is local, i.e. That decays rather rapidly with distance and also vanishes beyond about an hour’s travel time.

Short- and long-term effects of enclaves

The Swedish and Danish studies provide further info on the timing of enclave quality results on immigrant earnings. However, the evidence is mixed. While among the Danish researches finds consistent positive impacts over time (the evaluation covers two to 6 years after ~ immigration) <8>, the sweden study, spanning two to eight years after immigration, offers suggestive proof for the enclave quality effects to be cumulative in nature. That is, the latter study finds that the positive impact of life in a high-quality enclave boosts with time spent in the organize country and also begins to take result after roughly eight years following immigration <6>.

But what around effects in the really short term? immediately following arrival, enclave size might impede incoming immigrants’ job-finding success if the existence of co-ethnics to represent competition for jobs, fairly than a source of information. A united state study supplies a comparable policy experiment as the Scandinavian research studies to calculation the short-term effects of enclave dimension on job-finding prices of newly-arriving refugees and asylum-seekers <9>. Ninety days adhering to arrival, the employment rate of the recent immigrants is discovered to it is in negatively affected by the variety of other recently-arrived immigrants, if the number of co-ethnic immigrant that have actually arrived for 2 or an ext years positively affects your job-finding rates.

Ethnic enclaves in Europe and the US

Does the extent of residential country clustering amongst immigrants vary across counties? The answer to this question is complex by two concerns in particular. First, there is no agreement on how to measure up ethnic concentration. Second, over there is a restricted availability of appropriate data (by immigrant nationality and at geographically disaggregated levels).

Three studies report a similar measure of regional ethnic concentration for immigrant groups in the US, Sweden, and Germany. In particular, they specify ethnic enclaves as locations in i beg your pardon the population’s share of one ethnic group is greater than the re-superstructure of that team at the national level. The nationwide share serves together a benchmark since it is the share the one would suppose if an ethnic group was uniformly distributed across areas within a country. The US study reports the 48% of US citizens with a migrate background live in fairly high-concentration zip code areas in 1979, with far-reaching dispersion across ethnic groups (e.g., 83.8% that Mexicans, 49.6% that Italians, contrasted to just 25.8% of Greeks) <12>. The swedish study mirrors that in 1997, 42% that first-generation, i.e. Foreign-born, immigrants lived in ethnic enclaves <6>. Finally, the German study reports that among immigrants from the previous Yugoslavia, Italy, and Greece, around 40–50% resided in high-concentration counties in 1987, compared to only 21.2% amongst Turkish immigrants <13>.

The in its entirety levels of country clustering amongst immigrants therefore appear to it is in strikingly comparable in european countries and also the US, with roughly 40–50% that the particular immigrant population living in country enclaves.

Convincing empirical evidence of enclave impacts on immigrants’ labor industry integration is scarce. Currently reliable evidence (which very closely takes endogenous sorting right into account) is based predominantly on certain policy experiments worrying refugees and asylum-seekers in selected countries. Yet, countries vary in their immigration policies and the composition of the immigrant populations they attract. Consequently, the results may not it is in generalgimpppa.orgble come other groups of (labor) immigrants and other countries. Some evidence has started to emerge, but much more causal proof is essential for a wider set of immigrant groups and countries that examines both the impact of enclave size and also quality on financial integration.

While theoretical considerations indicate that living in one enclave can be beneficial for rapid labor industry integration in the quick term and also detrimental for financial progression in the lengthy term, empirical studies execute not categorically check this hypothesis. Rather, over there is some evidence for positive earning return to enclave high quality in the relatively long term, over a duration of as much as eight year after migration. One study even says that this positive impacts increase over time. It is vital to know more about the time pattern the enclave effects, beyond this timeframe and over generations.

Finally, future research study should address the question of the complex, basic mechanisms that connect enclave size and/or quality to immigrants’ labor market success. Proof so far is continuous with the idea of details spillovers via regional social interactions, through co-ethnics playing an important role. Hence, the is no unreasonable to suspect that word-of-mouth details from (especially successful and also highly-educated) co-ethnics would certainly be more efficient in help newly-arriving immigrants’ uncover a (better) task than formal information networks outside the enclave. Yet, research studies that attend to the residential sorting issue carry out only net estimates of the overall enclave effects, without testing specific mechanisms, together as information diffusion among local co-ethnic networks, or the function of enclave economic climates in providing jobs to newly-arriving immigrants. An ext evidence is because of this required to with a conclusive answer on the basic mechanisms at play.

Empirical evidence argues that immigrants advantage from life in areas with a big number of co-ethnics if the ethnic network is that high quality, i.e. If co-ethnics room well-educated, work-related in well-paid jobs, and if the employment price in the ethnic ar is high. Hence, labor sector integration can improve if newly-arriving financial migrants, refugees, and also asylum-seekers would resolve in communities with reasonably high average education and learning levels and reasonably high employment rates among the co-ethnic population.

Possible policies can include a targeted spatial dispersion of incoming refugees and also asylum-seekers throughout areas according to socio-economic characteristics, such as education levels and employment prices of the resident country populations. With respect to job migrants, policymakers might take into consideration the feasibility of plans that encourage and also incentivize especially the low-skilled immigrants to resolve in areas with reasonably high employed staff rates and also education levels amongst co-nationals.

Overall, enclave high quality (in terms of levels that income, standards of education, and rates that employment) is more important than enclave size for driving economic success. Policy should thus focus much less on preventing ethnic “ghettogimpppa.orgtion” per se, yet aim come discourage socio-economic residential segregation and also instead implement housing policies the promote blended residential areas in terms of high- and low-skilled workers.
