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 Genealogy Gems Premium member Katharine Ott wrote in this with newsworthy gem:
“Recent adoption records are being released in Ohio. Such an exciting time for those adoptees yearning to connect with their bloodlines! Before the bill took effect, they allowed birth mothers to redact their names. Out of 400,000 only around 110 took them up on that. There’s also a preference form with the birth records where the mother can request not to be contacted. I wonder how often that might not be respected. It’s such an interesting situation for someone to be in.”
Wow, that’s huge news about Ohio adoption records! Thanks for the news, Katharine. She sent us this link to a local news story that covers the story. The Ohio Department of Health posted this webpage about ordering adoption records.
Want to learn more about accessing adoption records in any state? Check out the U.S. Adoption Research page at the FamilySearch wiki for a terrific overview and helpful links.
Also, try running a Google search for the name of the state and the keywords adoption and genealogy. You’ll find lots of great resources, like this pageon adoption records at the Pennsylvania state library or this online resource from the State Historical Society of Missouri.

Do you ever find it difficult locate U.S. property owned by your ancestors? Two online resources for land ownership maps are available by subscription at HistoryGeo.com, which might just prove helpful!
The First Landowners Project aims to map out the original landowners in public land states. Currently, they’ve charted about 8.8 million original landowners from 21 different states (Alabama, Arkansas, California, Colorado, Florida, Iowa, Illinois, Indiana, Kansas, Louisiana, Michigan, Minnesota, Mississippi, Missouri, Nebraska, Ohio, Oklahoma, Oregon, Texas, Utah, Wisconsin). “We will continue to add more of the Western states soon,” says a recent press release. “Information on eastern states can be found on our frequently asked questions blog entry.” Watch a video demonstration of this project below. Click here to read a detailed description of it.
The Antique Maps Project is a growing collection of historical maps that contain names of U.S. landowners. Their comment: “Many of these maps are indexed and searchable, and the ones that are not will be (thanks to our volunteer labeling program).” Watch a video about this project below:

Opening pages of rare 1905 Sanborn Map of San Francisco, showing city just before 1906 earthquake. Find the entire map book at the David Rumsey Historical Map Collection
Genealogists rely on historical maps to help us navigate the geography of our ancestors’ lives. One of the most important resources available online is the David Rumsey Map Collection. Well, Rumsey recently announced on his website that he will be making more than 38,000 of his historical maps–everything he’s currently got online–available at the Digital Public Library of America (DPLA).
I blogged recently about the DPLA, which aims to create an enormous, free digital library we can all access online. It will be great to have the Rumsey map collection searchable on the DPLA so we can search these maps while we look for any other sources on any particular location our ancestors lived. “Maps tell stories that complement texts, images, and other resources found in the growing DPLA library,” says Rumsey. “And the open content policies of my online library fit perfectly with DPLA’s mission to make cultural resources freely available to all.” He applauds what the DPLA is trying to accomplish and even encourages other collectors to donate content.
Rumsey has spent years collecting thousands of old maps and putting them online. Now he’s working to share them even more widely. His entire collection of about 150,000 maps will eventually be housed at Stanford University. Meanwhile, we can all enjoy the thousands of images we can search on his site or at the DPLA.
