How to Find Enumeration District Maps
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.
For censuses before 1900, the government used voting districts as enumeration districts. Find voting district maps in the Library of Congress book, Ward Maps of the United States : A Selective Checklist of Pre-1900 Maps in the Library of Congress. (The links here lead to WorldCat search results for these titles. WorldCat will tell you about libraries that have these books.)
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.

Enumeration District (ED) Map Finder
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.
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.

The 1950 enumeration district maps are now available for free online. Read my article The 1950 Census for Genealogy and watch the video to learn how to access them for free.

10 Steps to Genealogy Success
1. Gather what you know
Start with yourself and work backwards. This provides a foundation for your research.
Compile all the information you already have about your family, including:
- names, dates, places of life events.
- Scour your house for records, photo albums, family bibles.
- Write down stories or anecdotes you’ve heard.
2. Get a genealogy software program
You need a place to put the information. Yes, you can build a family tree online, but it’s critical to have the main tree that you work on be the one on your computer. That way you own the files forever and you’re not reliant on an ongoing subscription or a group tree where others can change it.
There are a wide variety of genealogy software options, but the good news is you only need one.
It’s not a big investment. For less than $40 or $50 you can get a powerful program that can track everything you find, keep it organized, make it easily searchable, and even run reports and connect you to hints on your favorite genealogy websites.
Rootsmagic, Legacy Family Tree, Family Tree Maker and Reunion are some of the most popular and have been around the longest. I use RootsMagic https://rootsmagic.com/store/rootsmagic/
If free is more in your budget, try the Family Tree Builder by MyHeritage. https://www.myheritage.com/FP/ftb-welcome.php?lang=EN
3. Back up your computer
Make sure your computer is automatically backed up to the cloud.
- Backups need to be offsite so an external hard drive in your desk drawer won’t cut it.
- Sign up for a yearly plan, install it on your computer and forget about it.
- My favorite: Backblaze https://www.backblaze.com/landing/podcast-lisa.html
4. Interview your living relatives
It’s really important to take the time to talk with family members. You’ll want to gather information, uncover stories, and gain insights into your family history. Encourage them to share their memories, photos, and documents. And let’s be practical, it’s best to start with your oldest living relatives first. Prepare your questions ahead of time and record whenever possible.
5. Get familiar with AI tools
- Embrace AI-powered tools. Even if you don’t use them for anything else, there’s no denying that AI can dramatically speed up your research and do a ton of the heavy lifting.
- Get comfortable with at least one of the leading AI Chatbots. You can start out with the free version, and if you want more horsepower, subscribe for a low monthly fee.
- Leading options: ChatGPT, Grok, Google’s Gemini, Perplexity and Claude.
- Pick one, bookmark it on your web browser, and use it.
- AI and Genealogy playlist at the Genealogy Gems YouTube channel.
6. Know what you’re looking for
Once you’ve laid this foundation, you’re ready to make your first new discoveries. At first it will be easy to know what to work on because you’re still working backwards. Most of us can fill in most of the blanks on our grandparents. But then it’s time to move to your great grandparents and so on.
You’re going to focus first on finding ancestors. These are the people you are directly descended from: grandparents, great grandparents, and so on.
You’ll also be filling in the tree with your relatives. These are your aunts and uncles, cousins and so on. For each ancestral couple, take the time to find all their children. These people may feel more secondary, but the record of a great aunt might be the key to unlocking information about her parents that you couldn’t find by only researching her brother your grandfather. When it comes to all your relatives, that’s totally up to you. You can invest time on finding them now, or wait until you make more progress on your tree and then come back to them later when you have time.
7. Gather Foundational Records
You’re going to focus on essential milestones for each ancestor in your tree. Think of this information as the backbone of your family tree. You can add flesh to the bones later.
Start with the most recent event for that ancestor, which was probably their death if you’re working on a great grandparent, and then move back to their marriage, and then their birth.
From there, you’ll want to fill in some of the most important items such as:
- Their children (records: census, obituaries in newspapers, etc.)
- Where they lived throughout their life (records: census, city directories, voter registrations, etc.)
- Military service (records: draft cards, service records, pension records, etc.)
8. Leverage the power of search engines
While not everything is online by any stretch of the imagination, here are some of the best online sources to search for the records we just mentioned:
- FamilySearch – https://www.familysearch.org
All kinds of historical records, digitized books, and family tree info. - Find a Grave – https://www.findagrave.com
The world’s largest gravesite collection. - The National Archives – https://www.archives.gov
Governmental records (ex. military) - Chronicling America – https://chroniclingamerica.loc.gov
Digitized old newspapers. - Google Books – https://books.google.com
Over 25 million digitized books and printed materials.
You’ll also need to up your game with Google so that you can find things beyond just the most popular genealogy websites. And these skills will come in really handy with Google Books.
- Use search operators to target specific resources.
- Quotes around a word or phrase for exact matches.
- Use a minus sign in front of words you want to exclude from the results.
- Place an asterisk between two words within quotes to include a few words or initials between the exact phrase.
- There are many more search operators and strategies. These are covered in the wide range of Genealogy Gems videos. Visit https://lisalouisecooke.com/videos/ and click the “Google” category.
- Use Google Alerts to continue the searching for you 24/7. https://www.google.com/alerts
9. Put Flesh on the Bones
It’s time to put some flesh on the bones so to speak. In other words, creating a more comprehensive timeline for your ancestor. Your genealogy software probably has a timeline report feature. Pull it up or print it out and start filling in the gaps.
- Where they worked (records: census, city directories, industry catalogs, etc.)
- Land they owned (records: land records, tax records, probate records, etc.)
- If they immigrated from another country (records: passenger lists, citizenship papers, etc.)
- Photos (sources: family members, Google search, old photo databases, genealogy websites like Ancestry, MyHeritage, Findmypast and FamilySearch, etc.)
- Any other interesting life events (records: Newspapers, books, etc.)
10. Mastering the art of record interpretation
It’s not enough to find records. You’ve got to really understand what they are and are not telling you.
- Take the time to familiarize yourself with the record collection.
- Why was it created?
- Who created it?
- What timeframe does it cover?
- What doesn’t it include?
- Use AI tools to help you transcribe or translate records but always check for accuracy!
- Find out what the abbreviations used in the documents mean. (ex. Census instructions)
- Use multiple credible sources to verify the information you find.

Navigating the End of FamilySearch Microfilm Lending
Just announced: The FamilySearch microfilm lending service will end on August 30, 2017. Let’s cover what we know so far, how it may impact you, and strategies for getting the information you need.
WHAT: FamilySearch Microfilm Lending Ends
Most of the Family History Library’s microfilm vault has already been digitized and is online–or will be within a short time. According to the website:
“Over 1.5 million microfilms (ca. 1.5 billion images) have been digitized by FamilySearch, including the most requested collections based on microfilm loan records worldwide.”
However, the world’s largest lender of microfilmed genealogical records will be discontinuing the distribution of microfilms to Family History Centers in the near future.
“On September 1, 2017, FamilySearch will discontinue its microfilm distribution services,” announced the site yesterday. “The change is the result of significant progress in FamilySearch’s microfilm digitization efforts and the obsolescence of microfilm technology. Digital imaging has made it easier to find ancestors through the internet, mobile, and other technologies.”
This means the clock is now counting down your ability to borrow microfilmed genealogical records from the Family History Library. The last day you can place an order for delivery to your local Family History Center is August 31, 2017.
It’s a change I’ve seen coming, but it’s still a little disconcerting now that it’s here. But change is the norm in today’s busy world, so let’s break down the details we know so far together.
WHY: Why are they discontinuing microfilm lending before they’re done digitizing?
It’s just too expensive. “The cost of duplicating microfilm for circulation has risen dramatically, while demand has decreased significantly,” says a FamilySearch Q&A. “At the same time, it has become increasingly difficult and costly to maintain the equipment, systems, and processes required for film duplication, distribution, and access.” FamilySearch wants to redirect its microfilm lending resources to providing more and better electronic record access.
I have personally visited the microfilm distribution facility, and the best analogy I can give you is that it looks a bit like the inside of an Amazon warehouse. It’s a mammoth and expensive undertaking, certainly not something you open or close lightly. I’m thankful that in the decades before the Internet, FamilySearch devoted so many resources to helping all of us gain access to hard-to-find records from around the world.

WHEN: What will be available online and when
According to FamilySearch, they hope to finish digitizing the records that they have permission to digitize, in 2020. Unfortunately, some films we will not be digitized because of contractual limitations, data privacy, or other restrictions. Look to the Catalog for access details for the records you want.

HOW: How to order FamilySearch microfilms between now and August 31, 2017
I encourage you to use the microfilm lending service while it is still available. While most microfilmed records will be eventually digitized, the fate of a small percentage may remain unknown for some time. Follow these steps to view them now:
1. Go to FamilySearch.org and log in, or create a free login. (You’ll need the login to order records.)
2. Under the Search menu, select Catalog.
3. Search by location, listing first the largest jurisdiction (such as the country) and proceeding to the smallest, such as “United States, Illinois, Cook, Chicago.”
4. Review search results by clicking on the record categories and then each entry. Within the entries, watch for interesting items that only list microfilm or microfiche formats.
5. Within record entries, order items you want by clicking the microfilm reel icon on the far right, under Format. Select the lending period and the correct currency. It currently costs $7.50 USD to borrow a microfilm reel for 90 days.
During the order process, you’ll select a family history center near you to receive the item(s). When your order arrives, you’ll be notified. Check the center’s schedule before visiting; most have limited hours. Centers are free to use. When you get there, identify yourself and request your film. Then put it in the microfilm reader and scroll through it until you find the item number and pages you need. (Here’s a helpful article: How to Use a Microfilm Reader.)
What about accessing microfilmed records after August 31, 2017?
You’ll still have several options. Sunny Morton, author of the quick reference guide Genealogy Giants: Comparing the 4 Major Websites, says the FamilySearch catalog will still be a go-to resource:
“At this point, the Family History Library in Salt Lake City, Utah still plans to keep on hand microfilmed copies of records that are not yet online. So your options include going to view them in person (since to the best of our knowledge the library won’t be lending them), arrange for someone else to view them (such as through the Random Acts of Genealogical Kindness Facebook group), or use the FamilySearch Catalog to identify the records and then attempt to locate them through other repositories and websites.
To find records you may borrow from other sources, click where it says ‘View this catalog record in WorldCat for other possible copy locations’ [see screenshot below]. This will take you directly to this item’s listings in WorldCat, which is the enormous, free multi-library online catalog. Look either for a copy at a library near you, or a copy at a facility that participates in inter-library loan. (This is the same process you already have to use to find copies of books you can borrow, since the Family History Library doesn’t lend these, either.)”
What about accessing the digitized records?
After August 31, 2017 many genealogists will be turning to the online FamilySearch catalog and Family History Center Portal. (Learn more about the Portal at the FamilySearch Wiki.) As you attempt to view records through the portal, you may be prompted to go to a Family History Center to view the record, and the site will link you to a map of all locations. It’s important to understand the difference between an official Family History Center and an Affiliate Center. We’ve learned that Affiliate Centers do not have access to what is called the Family History Portal. That portal is only accessible from an officially designated Family History Center.
So how do you know which location on the map is official, and which is an affiliate? I turned to genealogy blogger and friend of Genealogy Gems Amie Tennant for clarification:
The (online) FamilySearch map of Family History Centers is not accurate. With the new changes to microfilm loans, this is going to be a big problem. In other words…if a person assumes all FHCenters are the same and travels to the nearest one, they will be sorely disappointed to realize that this one will NOT have access to all the digitized microfilm. (Researchers) should call ahead to confirm whether the center they see on this map is an affiliate or a full FHC with access to the portal.
I’ve reached out to FamilySearch for additional official information on this and several other important questions that have arisen with the discontinuation of microfilm lending. I’ll report to you here on the Genealogy Gems blog and the podcast as more information becomes available. Check out Amie’s article for more information on the various levels of access.
What do you think?
The end of the FamilySearch microfilm lending service is a major milestone. It signals exciting future online access, but provides obstacles for the next few years. What suggestions do you have for researchers to gain additional access to essential microfilm? Please share with the Genealogy Gems community in the Comments below.

Canadian census tips from Dave Obee:
The 1901 census is his favorite because it says for the first time where people had come from
He starts his searches on Ancestry.ca but census databases are free to search on Library and Archives Canada website
Marital status may not have been totally accurate. They only captured single or married or windowed. Divorced was not captured.
There are two different types of enumerations: de facto and de jure, and the rules were different.
This means your ancestor could be enumerated in multiple locations
