Unauthorized Immigrants in California: Estimates for Counties

By Laura Hill, Hans Johnson

Unauthorized immigrants make up 7 percent of California’s total population. But little is known about exactly where they live. This report presents the first authoritative estimates of this group within the state’s regions and counties. It shows the unauthorized living in all parts of California, with Shasta County housing the smallest share and the Monterey/San Benito County region the largest.

This report was supported with funding from the Silicon Valley Community Foundation.

Holding the Line? The Effect of Recent Border Build-up on Unauthorized Immigration

By Hans Johnson, Belinda Reyes, Richard Van Swearingen

Controlling unauthorized immigration along the U.S.-Mexican border has become an increasingly important national objective. Despite initial bipartisan support for this strategy, concerns about its effectiveness are beginning to emerge. This report addresses the following questions:

  • Has increased border enforcement changed decisions to migrate?
  • Has it changed where and how people cross the U.S.-Mexican border?
  • Has it led to an increase in migrant deaths?
  • Has it altered how long immigrants stay once they arrive?
  • Has it reduced the total number of unauthorized immigrants living in the U.S.?
  • What other policy options might help curb unauthorized immigration?

Lessons from the 2007 Legal Arizona Workers Act

By Steven Raphael, Sarah Bohn, Magnus Lofstrom

Arizona’s unauthorized immigrant population shrank after employers were required to verify workers' legal status with the federal E-Verify system. The 2007 law also pushed a substantial number of unauthorized immigrants into self-employment. The study estimates that from 2008 to 2009 Arizona’s population of unauthorized immigrants of working age fell by about 17 percent, or about 92,000 people, as a result of the Legal Arizona Workers Act (LAWA).

This research was supported with funding from the Russell Sage Foundation.

As farmworkers age, their health care needs are changing—and cost and lack of insurance are often barriers to care. While recent state and federal policies have made insurance more accessible, not all policies improved coverage among farmworkers.

The 2020 Census and Political Representation in California

By Eric McGhee, Sarah Bohn, Tess Thorman

If the 2020 Census does a poor job of counting traditionally undercounted populations and immigrant communities, the state could easily lose one of its 53 seats in the House of Representatives.
