 At one of the peaks of its population, the 1910 census had 40.6% of its population of 88,098 as foreign-born, with 89.3% of the population being either foreign-born or having at one or both of their parents as foreign-born.70.6% of all voters were foreign-born, and only 5.1% of voters were native-born with native parents.This amalgam of immigrants from dozens of countries created a unique culture, especially once population growth stopped, and the county shrank in population to its current numbers.
