United States Census, 1880

The 1880 United States census, conducted by the Census Office during June 1880, was the tenth United States census. It was the first time that women were permitted to be enumerators. The Superintendent of the Census was Francis Amasa Walker. This was the first census in which a city—New York City—recorded a population of over one million, and the first census in which the 20 most populated cities all recorded over 100,000 residents.
