My 1950 U.S. Census Release To-Do List: May 1 = Moving Day

This year, I'm taking steps to find a street address for each key ancestor enumerated in the 1950 U.S. Census. I want to be ready to find them when the unindexed Census records are made public in 2022.

Even when I do find these ancestors in the Census (browsing images in the Enumeration District where each lives), I have to remember that within a month, some city-dwellers could be living elsewhere.

The Tradition of Moving Day

In the Big Apple, May 1 was when all rental leases expired. The same was true in Chicago for many years, and other big cities as well.

Families that lived in apartments spent the weeks before May 1 talking with new landlords who might be willing to negotiate rents or offer another incentive to move. Renters also signed contracts to have moving companies lug furniture to the new place on Moving Day.

Moving Day is unlikely to change where I look for my urban ancestors in the 1950 Census, since they were probably counted in the early days and weeks of enumeration. But it does remind me that the 1950 Census address might be only one in a long line of address changes for each ancestor.

Look for an address after May 1949

My recently married parents (Harold Burk and Daisy Schwartz) were in their second New York City apartment by the time of the 1950 Census. Their parents and other relatives, however, weren't necessarily living in the same apartment in April of 1950 as they were in April of 1949.

Similarly, in the Chicago branch of my family, many were renters. From one Census to another, I noticed that many of these ancestors changed apartments--and very likely they moved more than once in the decade between each Census Day.

So as I research my New York City and Chicago ancestors who were renters, I'm trying to find addresses after May of 1949. I'm looking at birth records of their post-WWII babies, city directories, phone directories, advertisements, news articles, and social items in the newspaper, among other sources.

Ancestors in 19th Century Mortality Schedules

Looking for the deaths of 19th century ancestors in America?

Check the U.S. Census Mortality Schedule, one of the non-population schedules.

In 1850, 1860, 1870, and 1880, enumerators asked about people who died in the 12 months before Census Day (which at that time was June 1st).

Not all of these schedules still exist for every state. Where they exist, some mortality schedules are in state archives and state libraries. Many are available via Ancestry and Family Search. Just as one example, it's easy to browse or search the 1850 Mortality Schedules for many states at Family Search and at Ancestry.

The best part is--if you find an ancestor in one of these mortality schedules, you'll learn a lot about that person.

Above, the 1880 Mortality Schedule for Fairfield county, Ohio, where the very first line has my husband's ancestor, Abel Everitt. He was a farmer, born in Pennsylvania, father born in New Jersey and mother born in ... Ireland (no county named, alas). I found out his month of death (April, 1880), cause of death (apoplexy), and even more details from this page.

Knowing the place and date, I soon located the ancestor's burial place and from there, I was able to add a few more names to the family tree.

Dara asks whether Mortality Schedules are usually indexed. I've found most are . . . but still I may browse if I haven't found an ancestor who I suspect should be there. Unfortunately even if an ancestor did die in the 12 months prior to Census Day that person may not always be listed on the Mortality Schedule.

Census Day Wasn't Always April 1st

Who cares when the Census was taken? 

Turns out, knowing when Census Day falls can be helpful in narrowing down possible birth, marriage, and death dates.

One New York ancestor was enumerated with her parents in the 1900 US census, then with her husband in the 1905 NY state census, taken on June 1st. By searching between June, 1900 and May, 1905, and using creative spelling, I was able to find her marriage in early 1905.

By the time of the 1910 US census, she and her husband had one daughter...later that year, after Census Day, another daughter was born who wouldn't show up in a NY state census until 1915.

For the upcoming release of the 1950 US Census, I was particularly interested that enumerators were required to fill out a separate Infant Card for every baby born in January, February, or March of that year. If someone was born in the census year of 1950 a few days or weeks before the Census Day of April 1st, there will be an Infant Card for that person, loaded with extra details about the parents and the baby!

Census Day Was Not Always Fixed

As shown in the graphic at top, Census Day wasn't always one fixed date. Early in the nation's history, enumerators visited households to record information as of the "first Monday in August." The idea was to avoid taking farmers out of the fields during planting or harvesting.

In 1830, Census Day was standardized as June 1st, another date that didn't conflict with agricultural responsibilities.

In 1910, the date was changed to April 15th...in 1920, the date became January 1st...and then, in 1930, the date was fixed as April 1st, where it remains.

I like to keep this list of Census Day dates handy so I can correlate with other clues as I research my family's past.
