By executing the script master_script.do, a user can replicate all results, provided s/he has the necessary dependencies (i.e. extremely large data files that are not distributable via GitHub, but are included in the supplementary materials at the journal's website). Specifically, these files are:

• acs_09_16.dat.gz (ACS microdata for years 2009-2016)
• bpl_vars_80.dat.gz (1980 Census 5% sample for computing foreign exposure in 1980)
• forshr_vars_80_10.dat.gz (1980, 1990, and 2000 Censuses 5% samples, plus 2010 ACS 1% sample, for computing decadal changes in foreign exposure)
• statecontrols.dat.gz (1978-2011 March CPS, for computing time-varying state characteristics)
