Dear IPUMS User,

25 years ago, on a brisk Minnesota morning in early November, Steve Ruggles and the small but mighty original IPUMS team released their first dataset. The original Integrated Public Use Microdata Series included harmonized versions of the 1880, 1900, 1910, 1940, 1950, 1960, 1970, 1980, and 1990 U.S. Censuses. The first download of those data occurred on November 19, 1993. ("We didn't have a lot of traffic in those days," Steve remarked.) Since then, IPUMS has become the world's largest accessible database of census microdata, covering more than 100 countries and over 2 billion records. The team is now more than 100 people, and we've reached more than 100,000 users worldwide. .  

We are celebrating this milestone — but we need your assistance. If IPUMS has helped you, consider helping IPUMS. Here are a few ways you can participate.
