In this paper, we compare the reliability of migration estimates from two rather different macroeconomic periods in recent U.S. history. One of these periods, 1985-1990 coincides with the culmination of a vast industrial restructuring which saw a significant decline in manufacturing employment. The other period, 1995-2000, encompasses a time of robust economic growth and tight labor markets driven by productivity gains associated with new technologies. Our interest here is in the stability of common individual-level predictors of migration in these rather disparate macroeconomic contexts. Using confidential internal versions of the 1990 and 2000 Census long-form data, we estimate logistic models of the likelihood that individuals will migrate. The geographic detail in the internal Census data permits us to measure migration in ways that are not possible with public-domain Census data on persons. We develop migration definitions that distinguish between local residential mobility likely associated with life course transitions from migration out of the labor market area that may be driven more by employment and other socioeconomic considerations. Using logistic modeling, we find that the same individual attributes predict migration reasonably well during both periods. We also compute some illustrative probabilities of migration that show temporal stability in migration predictors could be lessened by certain changes in population composition.

RESIDENTIAL MOBILITY ACROSS LOCAL AREAS IN THE UNITED STATES AND THE GEOGRAPHIC DISTRIBUTION OF THE HEALTHY POPULATION
February 2014
Working Paper Number:
CES-14-14
Determining whether population dynamics provide competing explanations to place effects for observed geographic patterns of population health is critical for understanding health inequality. We focus on the working-age population where health disparities are greatest and analyze detailed data on residential mobility collected for the first time in the 2000 US census. Residential mobility over a 5-year period is frequent and selective, with some variation by race and gender. Even so, we find little evidence that mobility biases cross-sectional snapshots of local population health. Areas undergoing large or rapid population growth or decline may be exceptions. Overall, place of residence is an important health indicator; yet, the frequency of residential mobility raises questions of interpretation from etiological or policy perspectives, complicating simple understandings that residential exposures alone explain the association between place and health. Psychosocial stressors related to contingencies of social identity associated with being black, urban, or poor in the U.S. may also have adverse health impacts that track with structural location even with movement across residential areas.

Leaving Home: Modeling the Effect of Civic and Economic Structure on Individual Migration Patterns
June 2002
Working Paper Number:
CES-02-16
This research analyzes the effect of community structure upon individuals' probabilities of moving between 1985 and 1990. Using the full Census sample long form microdata for 1990, we re-allocate adult persons in 1990 to their 1985 county of residence. Then, using origin county macro-structural variables (derived from the Economic Census microdata) and individual characteristics (from Decennial Census microdata), we develop a two level hierarchical linear model. In level 1, we construct a logistic equation modeling individual probabilities of moving. In level 2, we model the contextual effects of origin community structure on these models. These contextual effects fall into two categories: 1) economic conditions that comprise the usual aggregate 'push' factors and 2) civic community factors that act to retain people in their community. Results specify the relationship between community context and individual migration patterns, and demonstrate effects of local economic structure and local civic structure on these individual probabilities. Most notably, we find that civic attributes of communities are associated with a propensity to stay in place, net of community economic factors and individual characteristics.

Foreign-Born and Native-Born Migration in the U.S.: Evidence from IRS Administrative and Census Survey Records
July 2018
Working Paper Number:
carra-2018-07
This paper details efforts to link administrative records from the Internal Revenue Service (IRS) to American Community Survey (ACS) and 2010 Census microdata for the study of migration among foreign-born and native-born populations in the United States. Specifically, we (1) document our linkage strategy and methodology for inferring migration in IRS records; (2) model selection into and survival across IRS records to determine suitability for research applications; and (3) gauge the efficacy of the IRS records by demonstrating how they can be used to validate and potentially improve migration responses for native-born and foreign-born respondents in ACS microdata. Our results show little evidence of selection or survival bias in the IRS records, suggesting broad generalizability to the nation as a whole. Moreover, we find that the combined IRS 1040, 1099, and W2 records may provide important information on populations, such as the foreign-born, that may be difficult to reach with traditional Census Bureau surveys. Finally, while preliminary, the results of our comparison of IRS and ACS migration responses shows that IRS records may be useful in improving ACS migration measurement for respondents whose migration response is proxy, allocated, or imputed. Taking these results together, we discuss the potential application of our longitudinal IRS dataset to innovations in migration research on both the native-born and foreign-born populations of the United States.

Dynamics of Race: Joining, Leaving, and Staying in the American Indian/Alaska Native Race Category between 2000 and 2010
August 2014
Working Paper Number:
carra-2014-10
Each census for decades has seen the American Indian and Alaska Native population increase substantially more than expected. Changes in racial reporting seem to play an important role in the observed net increases, though research has been hampered by data limitations. We address previously unanswerable questions about race response change among American Indian and Alaska Natives (hereafter 'American Indians') using uniquely-suited (but not nationally representative) linked data from the 2000 and 2010 decennial censuses (N = 3.1 million) and the 2006-2010 American Community Survey (N = 188,131). To what extent do people change responses to include or exclude American Indian? How are people who change responses similar to or different from those who do not? How are people who join a group similar to or different from those who leave it? We find considerable race response change by people in our data, especially by multiple-race and/or Hispanic American Indians. This turnover is hidden in cross-sectional comparisons because people joining the group are similar in number and characteristics to those who leave the group. People in our data who changed their race response to add or drop American Indian differ from those who kept the same race response in 2000 and 2010 and from those who moved between a single-race and multiple-race American Indian response. Those who consistently reported American Indian (including those who added or dropped another race response) were relatively likely to report a tribe, live in an American Indian area, report American Indian ancestry, and live in the West. There are significant differences between those who joined and those who left a specific American Indian response group, but poor model fit indicates general similarity between joiners and leavers. Response changes should be considered when conceptualizing and operationalizing 'the American Indian and Alaska Native population.'

Foreign-Born Out-Migration from New Destinations: The Effects of Economic Conditions and Nativity Concentration
April 2010
Working Paper Number:
CES-10-09
Immigrants living in new destinations in 1995 were 2.5 times more likely to undertake a labor market migration by 2000 as those living in traditional places. This paper looks at two competing explanations for immigrants' differential secondary migration, namely nativity concentration versus labor market context. Utilizing confidential Census data for 1990 and 2000, we examine out-migration from 741 labor markets that cover the entire country and develop new destination classifications specific to the growth and composition patterns of foreign-born from the largest Asian, Latin American and Caribbean foreign-born groups, and Canadians. The hypothesis guiding the analysis was that immigrants would be less likely to leave labor markets that have both robust economic conditions and high levels of compatriot affinity as measured by nativity concentration. The combined and group models provide strong support for the argument that immigrant's out-migration decisions respond both to local labor market economic conditions and compatriot availability, net of human capital and national origin.

Migration and Dispersal of Hispanic and Asian Groups: An Analysis of the 2006-2008 Multiyear American Community Survey
October 2011
Working Paper Number:
CES-11-33
This report seeks to evaluate selective migration processes of Hispanic and Asian nationality groups in the US from established settlement areas, using recent migration data from the American Community Survey. The underlying goal is to detect migration tendencies leading toward an increased dispersion of these groups associated with their migration processes. Using descriptive statistics, maps, and migration models, we assess how migration processes in the 2006-8 period are leading to the dispersal of Hispanic and Asian race ethnic groups across metropolitan areas, with special attention to the roles of co-ethnic communities and spatial assimilation. These analyses employ migration data available from the 3-year 2006-8 American Community Survey using restricted data from the US Census Bureau's Research Data Centers. This use of the restricted ACS files permitted the first post 2000 analysis of inter-metropolitan migration for Hispanic groups (Mexicans, Puerto Ricans, Cubans, Salvadorans, Dominicans) and Asian groups (Chinese, Indians, Filipinos, Vietnamese, Koreans) using the detailed demographic and geographic attributes available with these files. The data and analysis presented here provide a benchmark for further research of this kind with the American Community Survey in light of the fact that migration data will no longer be available from the US decennial census. The study examines migration from these groups' major settlement areas to other metropolitan area destinations as they are affected by the attraction of co-ethnic communities and by a migrant selectivity pattern consistent with the perspective of spatial assimilation. The migration processes themselves were evaluated in terms of two components: the out--migration rates of residents, and the destination selection of movers. From the perspective of co-ethnic community attraction, it was hypothesized that the outmigration rates from high co-ethnic settlement areas would be lower than those from areas where the group had a smaller overall presence and that the destination selections of out-migrants would be positively affected by the presence of high co-ethnic population shares in destination areas. From the spatial assimilation perspective, it was hypothesized that out-migration from high coethnic areas would least likely occur for group members with lowest education, poor facility with English, and recently arrived in the US; whereas the selection of destinations with large coethnic population shares would be most likely to occur for these same population categories. The results strongly confirm that co-ethnic community attraction continues to reduce outmigration of groups from major settlement origins and positively influences their destination selections. A series of multivariate migrant destination selection models confirm a consistent draw of ethnically similar destinations across individual Hispanic and Asian groups when other economic, demographic and structural metropolitan attributes are taken into account. In contrast, results regarding spatial assimilation are typically mixed or nonexistent in characterizing both out-migration and mover destination selectivity patterns. In fact, we find contrary evidence for some Asian groups for whom it is the most educated, and native born migrants who show a penchant for selecting destinations with greater co-ethnic population shares. Among the greatest destinations for Indians, for example, are Philadelphia, Seattle, Dallas, Boston and Atlanta- areas with higher than average Indian population shares, and areas that also house knowledge-based industries. The selection of co-ethnic destinations among Hispanic group migrants appears somewhat impervious to education attainment and Hispanic and Mexican group movers, who are foreign born and who arrived since 2000, are least, rather than most, prone to select co-ethnic destinations. The mover destination models make plain that employment growth at destination provides a strong draw for all Hispanic groups. This suggests that recent growth in low skilled jobs in parts of the country with small Hispanic populations are nonetheless attracting newly arrived, and less skilled Mexicans and other Hispanics who might have previously been especially lured to destinations with large co-ethnic population shares.

Geographic Immobility in the United States: Assessing the Prevalence and Characteristics of Those Who Never Migrate Across State Lines Using Linked Federal Tax Microdata
March 2025
Working Paper Number:
CES-25-19
This paper explores the prevalence and characteristics of those who never migrate at the state scale in the U.S. Studying people who never migrate requires regular and frequent observation of their residential location for a lifetime, or at least for many years. A novel U.S. population-sized longitudinal dataset that links individual level Internal Revenue Service (IRS) and Social Security Administration (SSA) administrative records supplies this information annually, along with information on income and socio-demographic characteristics. We use these administrative microdata to follow a cohort aged between 15 and 50 in 2001 from 2001 to 2016, differentiating those who lived in the same state every year during this period (i.e., never made an interstate move) from those who lived in more than one state (i.e., made at least one interstate move). We find those who never made an interstate move comprised 75 percent of the total population of this age cohort. This percentage varies by year of age but never falls below 62 percent even for those who were teenagers or young adults in 2001. There are also variations in these percentages by sex, race, nativity, and income, with the latter having the largest effects. We also find substantial variation in these percentages across states. Our findings suggest a need for more research on geographically immobile populations in U.S.

Individual Changes in Identification with Hispanic Ethnic Origins: Evidence from Linked 2000 and 2010 Census Data
August 2018
Working Paper Number:
carra-2018-08
Population estimates and demographic profiles are central to both academic and public debates about immigration, immigrant assimilation, and minority mobility. Analysts' conclusions are shaped by the choices that survey respondents make about how to identify themselves on surveys, but such choices change over time. Using linked responses to the 2000 and 2010 Censuses, our paper examines the extent to which individuals change between specific Hispanic categories such as Mexican origin. We first examine how changes in identification affect population change for national and regional origin groups. We then examine patterns of entry and exit to understand which groups more often switch between a non-Hispanic, another specific origin, or a general Hispanic identification. Finally, we profile who is most likely to change identification. Our findings affirm the fluidity of ethnic identification, especially between categories of Hispanic origin, which in turn carries important implications for population and compositional changes.

WHY IMMIGRANTS LEAVE NEW DESTINATIONS AND WHERE DO THEY GO?
June 2013
Working Paper Number:
CES-13-32
Immigrants have a markedly higher likelihood of migrating internally if they live in new estinations. This paper looks at why that pattern occurs and at how immigrants' out-migration to new versus traditional destinations responds to their labor market economic and industrial structure, nativity origins and concentration, geographic region, and 1995 labor market type. Confidential data from the 2000 and 1990 decennial censuses are used for the analysis. Metropolitan and non-metropolitan areas are categorized into 741 local labor markets and classified as new or traditional based on their nativity concentrations of immigrants from the largest Asian, Caribbean and Latin American origins. The analysis showed that immigrants were less likely to migrate to new destinations if they lived in areas of higher nativity concentration, foreign-born population growth, and wages but more likely to make that move if they were professionals, agricultural or blue collar workers, highly educated, fluent in English, and lived in other new destinations. While most immigrants are more likely to migrate to new rather than traditional destinations that outcome differs sharply for immigrants from different origins and for some immigrants, particularly those from the Caribbean, the dispersal process to new destinations has barely started.
