Looking for enumeration district maps for the U.S. Federal Census? You’re not alone!
1940 Census Enumeration District Map, Oklahoma, Wagoner County, http://research.archives.gov/description/5836456
Recently Genealogy Gems podcast listener Michelle in Denver, Colorado, wrote in with this question:
“Where can I find individual enumeration district maps? I don’t need a state-wide map showing the divisions between enumeration districts, but a map showing the numbered households within a single enumeration district.”
My answer: How to find Enumeration District Maps
First, here’s a little back story from the National Archives (U.S.) website:
“An enumeration district, as used by the Bureau of the Census, was an area that could be covered by a single enumerator (census taker) in one census period. Enumeration districts varied in size from several city blocks in densely populated urban areas to an entire county in sparsely populated rural areas.
Enumeration district maps show the boundaries and the numbers of the census enumeration districts, which were established to help administer and control data collection. Wards, precincts, incorporated areas, urban unincorporated areas, townships, census supervisors` districts, and congressional districts may also appear on some maps. The content of enumeration district maps vary greatly.
The base maps were obtained locally and include postal route maps, General Land Office maps, soil survey maps, and maps produced by city, county, and state government offices as well as commercial printers. Census officials then drew the enumeration district boundaries and numbers on these base maps.” (Check out the full article here.)
Enumeration district maps are not available in all years and all locations. 1940 ED maps are available on the National Archives (U.S.) website. (Scroll down to item 3 for instructions on getting to these through the Online Public Access search.) You’ll see that only the enumeration district numbers and street names are marked on the maps. Individual homes are not.
You might be wondering, are there enumeration district maps before 1940? They are limited but the answer is yes. Enumeration District maps are also available for the 1900 through 1930 censuses. You can browse and download the maps for free at FamilySearch. Search for title The United States enumeration district maps for the twelfth through the sixteenth US censuses, 1900-1940.
Next, turn to the book Cartographic Records of the Census Bureau for a listing of maps available back into the 19th century at the National Archives. It’s available as an ebook which you can read online or download for free from Google Books. This book is an invaluable resource for finding much early maps at available at the National Archives on microfilm.
If you just want to find the enumeration district number of an address you already know, go to the Unified Census ED Finder at Steve Morse’s One-Step genealogy website.
At the top of the Unified Census ED Finder page start by selecting the census year (currently 1870 through 1950.) Next, enter as much information as you know about the location such as the county. Select the city from the list of cities displayed. You will then be able to enter street-level information. If you select “other” from the city list, you can then type in the city or town name. Continue to follow the prompts and instructions.
Here are a few more things to keep in mind as you find and use ED maps:
In cities, there are often two columns of numbers in the census population enumeration (typically on the far left of the page). There’s house number and the number representing the order in which the enumerator visited the house (which has nothing to do with the house number). If you can’t find a relative in once census, pull the address from one census and use it in the Steve Morse database above to pull up the enumeration district for your missing decade.
Sanborn Fire Insurance Maps can be helpful when searching for old Enumeration District Maps.
Depending on the year you are researching, try to locate a Sanborn fire insurance map for the area. Sanborn maps do include drawings of individual homes and include their house number. Genealogy Gems Premium Podcast Episode 47 is all about Sanborn fire maps. On the show notes page I even include a list of links to many Sanborn map collections, organized by state.

Recently I heard about a slew of WWII documents at The National Archives [U.K.], some newly available online. Look closely at the descriptions: they have holdings of records of non-British forces, too!

Recently The National Archives [UK] promoted some of the WWII documents in its vaults, in commemoration of the 75th anniversary of the Battle of Britain. Below are resources and collections they’ve highlighted.
Royal Air Force combat reports. These are “official reports which pilots or air gunners filed after they had encountered enemy aircraft on operational flights,” says a description on the site. “The reports cover action seen by the squadrons, wings and groups serving with Fighter Command, Bomber Command, Coastal Command and the Fleet Air Arm. Now held at The National Archives in series AIR 50, they include Commonwealth, United States Army Air Force and Allied units based in the United Kingdom during the Second World War.”
Royal Air Force operations record books for squadrons. “Most of them date from the Second World War but there are some from the 1920s and 1930s and a few from the First World War,” says the site. “The ORBs, in series AIR 27, were created to provide a complete record of a unit from the time of its formation. Each book includes an accurate record of operations carried out by the unit. This online collection also includes some operations record books for dominion and Allied Air Force squadrons under British Command.” Part of the series is viewable online.
Welcome to this step-by-step series for beginning genealogists—and more experienced ones who want to brush up or learn something new. I first ran this series in 2008-2009. So many people have asked about it, I’m bringing it back in weekly segments.
In our first segment we’re going to get acquainted with the largest repository of genealogy materials in the world: The Family History Library in Salt Lake City, Utah. It’s free and available to the public and I’m going to get you ready to make good use of it through the online Family History Library catalog. Click on the show notes link, above, to read some great updates since the episode aired on how to use the online catalog and growing collection of digital records.
Then in our second segment my guest is Don R. Anderson, Director of the Family History Library, who describes the evolving direction of the Family History Library and its host site, FamilySearch.org.
You have precious family history files, both physical and digital. Have you ever wondered if they are in the proper form for safe, long term preservation? Consider taking a cue from the United State’s oldest federal cultural institution and the largest library in the world, holding more than 158 million items in various languages, disciplines and formats.
According to their announcement today the Library of Congress today released “a set of recommended formats for a broad spectrum of creative works, ranging from books to digital music, to inform the Library’s acquisition practices. The format recommendations will help ensure the Library’s collections processes are considering and maximizing the long-term preservation potential of its large and varied collections.”
What I like about this recommendations is that they rank the various file formats on the digital side of things in order of preference. So even if you aren’t in the position to change your digital file’s format right now, you will know where it falls in the spectrum of long-term preservation.
For example, here are the recommendations for digital photograph files formats in the order of preference:
