Under Laughlin’s guidance the Committee recommended—and Congress passed—the Johnson-Reed Immigration Restriction Act of 1924. The law capped immigration quotas for all nations at low levels (2%) and especially slowed the migration of the foreign born from places such as eastern and southern Europe (Russia, Poland, Italy, and the Balkans). According to Laughlin, the unfit and insane constituted an excessively large proportion of the national population in these regions. The act all but ended immigration from East Asia and the Indian Subcontinent.
