The 72-Year Rule and The 1950 U.S. Federal Census

When the 1940 U.S. Federal Census was released to the public in April 2012, immediately people began asking "When will the 1950 Census be available?" 

To that we must reply: "Great question... The National Archives and Records Administration will release it on April 1, 2022. I know... it seems like a long, long time."

"But why 2022," you ask?  "The 72-Year Rule," we reply. 

So what is this "72-Year Rule" anyway?  Another great question...

“The 72-year Rule” is governed by Public Law 95-416, enacted by Congress in October 1978 and “mandates that…federal census returns are kept confidential until 72 years after the census to which they pertain.”

Did You Know?

There are approximately 3.9 million individuals noted on the 1860 U.S. Census Slave Schedule. That is about 40% of the population of the southern states at the time. 

You may search the Slave Schedules by Owner Name and/or Location, but Browsing can provide broader insight into the areas where your ancestors may have been living. What was the make up of other homes, farms, or plantations surrounding the location where your ancestor was living (i.e., small family homes/farms with only a few slaves and servants vs. large plantations with large numbers of slaves and servants)?

Browse the 1860 Slave Schedule:

  1. Click "Search Now" in the Census collection box on the Home page
  2. Scroll to the "Included data collections"
  3. Select the "1860 U.S. Federal Census - Slave Schedules"
  4. On the right side of the page, choose a state from the drop-down menu
  5. Select from the County list
  6. Select from the available list of Townships

The page will refresh to display the slave schedule for that state, beginning on page one.
