Los Angeles County (CA)
Top countries of origin for this county's foreign-born population, decade by decade, 1900-1960 -- the same IPUMS NHGIS census tables behind Population Trends, read for country-of-birth instead of race. No comparable county-level series exists past 1960 in this data (same real gap Population Trends names for its own 1960-2023 span).
