State demographic data calculated by Dr. James Bachmeier, Associate Professor at Temple University.

  1. Estimates of parents with undocumented immigrant status were calculated using combined sample multiple imputation. The American Community Survey 2018 was merged with the Survey of Income and Program Participation (SIPP). Details of the methodology are described in Estimating the Characteristics of Unauthorized Immigrants Using U.S. Census Data: Combined Sample Multiple Imputation, The Annals of the American Academy of Polictical and Social Science, 2018. Estimates were adjusted for undercount, based on estimates in Unauthorized Immigrants in the United States, Migration Policy Institute, 2020.
  2. Lawful permanent residents (LPRs), also known as "green card" holders, are non-U.S. citizens who are lawfully authorized to live permanently within the United States.
  3. Estimates of parents with LPR status were calculated using combined sample multiple imputation. The American Community Survey 2018 was merged with the Survey of Income and Program Participation (SIPP). Details of the methodology are described in Estimating the Characteristics of Unauthorized Immigrants Using U.S. Census Data: Combined Sample Multiple Imputation, The Annals of the American Academy of Polictical and Social Science, 2018. Estimates were adjusted for undercount, based on estimates in Unauthorized Immigrants in the United States, Migration Policy Institute, 2020. Described in more detail in previous footnote for undocumented status imputation.
  4. ICE detainers are formal written requests from Immigration and Customs Enforcement to local jails and law enforcement requesting that they hold possible offenders for an additional 48 hours after their relsease date. Their purpose serves to allow ICE time to process the case and determine whether or not to take certain individuals into federal custody for deportation. Either all, some or none of the counties with the highest immigrant populations have a policy not to honor some or all ICE detainer requests.
  5. 287(g) Agreements deputize local law enforcement to perform some of the same functions as federal immigration officials. The jail model allows local law enforcement officials to perform more limited functions in jails, such as accessing federal immigration databases, arresting and detaining individuals for suspected immigration violations.
  6. The Warrant Service Officer (WSO) model was developed by the 287(g) program to allow jurisdictions to participate in a more focused cooperative agreement with ICE. As set forth in the Standard Operating Procedures of the Warrant Service Officer Memorandum of Agreement, participating entities of local law enforcement officers are trained, certified, and authorized by ICE to perform limited functions of an immigration officer within the law enforcement agency’s jail and/or correctional facilities. ICE provides a training program conducted by certified instructors at a location most convenient for the participating local enforcement agency.
  7. Allows unauthorized immigrants to apply for driver's licenses and state ID cards; these licenses and IDs are not to be used for federal identification purposes.
  8. In general, legal permanent residents (or green card holders) who entered the U.S. on or after August 22, 1996 must wait five years after obtaining LPR status to become eligible for many public benefits. Some states provide these benefits, with state funds, during this "five-year bar".
