Thanks for the link to this information. Is it weird that I got excited about an article on the history of small area census data? -- Chris Salvano From: Maps-L: Map Librarians, etc. <[log in to unmask]> On Behalf Of Joel Kovarsky Sent: Thursday, September 10, 2020 1:34 PM To: [log in to unmask] Subject: Re: Census mapping Some history of tracts: https://www.census.gov/history/www/programs/geography/tracts_and_block_numbering_areas.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.census.gov_history_www_programs_geography_tracts-5Fand-5Fblock-5Fnumbering-5Fareas.html&d=DwMDaQ&c=Oo8bPJf7k7r_cPTz1JF7vEiFxvFRfQtp-j14fFwh71U&r=UQQPWVNmMldzblsiu250sFlUilZ_9WQQiRmZC8lK6Tc&m=yT8b7A8k_H0LXTvZ31psVfYxlhEksSNudZd_SvtpGB8&s=yFWsLH9l_dTZEkQn_1fbzxYgic0pNCSpxQyvWiotlAs&e=> .

Only a handful of the larger cities were tracted in 30, but in 40 most big cities were divided into tracts. In Colorado, only Denver had tracts in 40. Most suburban areas were not given tracts at all, though parts of Los Angeles County outside the city were. By 1950 the use of tracts finally began to grow. In the earlier years the Census Bureau often used "Enumeration Districts" to break up populous areas. I know the National Archives in College Park, Maryland, has copies of maps with those census enumeration districts - and many of them were scanned on-line. You may want to contact them if such maps would be helpful to you.
