Methodology in Brief:
MPI’s method uses information from the SIPP to assign legal status to noncitizens in the ACS. In the SIPP, noncitizens report whether they currently have lawful permanent resident (LPR) status—i.e., a green card. Those without LPR status may be recent refugees, temporary visitors (e.g., students or high-skilled H-1B workers), or unauthorized immigrants. Our method maps characteristics such as country of birth, year of U.S. entry, age, gender, and educational attainment between the two surveys, and those noncitizens in the ACS who have characteristics similar to those reporting LPR status in the SIPP are coded as LPRs in the ACS. The remaining noncitizens—who are similar in characteristics to those not reporting LPR status in the SIPP—are classified as either unauthorized or legal temporary migrants, depending on whether they meet the qualifications for H-1B and the other temporary visa classifications. This method was developed in consultation with James Bachmeier of Temple University and Jennifer Van Hook of The Pennsylvania State University, Population Research Institute. For more detail on the methods, see Jeanne Batalova, Sarah Hooker, Randy Capps, and James D. Bachmeier, DACA at the Two-Year Mark: A National and State Profile of Youth Eligible and Applying for Deferred Action (Washington, DC: MPI, 2014). Please note that these estimates use commonly accepted benchmarks from other research studies to determine the size of the unauthorized population and response rates to surveys. These estimates have the same sampling and coverage errors as any other survey-based estimates that rely on ACS and other Census Bureau data.
