1950 US Census Maps – How to Find and Use Them

by Lisa Cooke | Nov 16, 2021 | 01 What's New, 1950, Census, Elevenses with Lisa | 4 comments

In Elevenses with Lisa episode 79 Lisa Louise Cooke explains:

How to find 1950 US Census Enumeration District (ED) Maps
The purpose behind them and how to interpret the maps
Ways to use the maps for your genealogy

This is a follow up to episode 51 on The 1950 Census for Genealogy. In that episode I discussed the importance of finding your ancestors’ enumeration district numbers in order to be able to find them when the digitized images are released (before the index is available.) In this episode I will walk you through how to locate the enumeration district (ED) number and then find the actual 1950 US Census ED map. We’ll wrap things up with a quick update on the release of the 1950 US Federal Census.

As I mentioned in Elevenses with Lisa episode 51 The 1950 Census for Genealogy, prior to 1880, U.S. Marshalls were the enumerators for the federal decennial census. Starting with the 1880 census enumerators were hired and they were each assigned an enumeration district, also known as an ED. These districts had to be mapped out so that the enumerators knew the area they were responsible for counting. Therefore, maps are drawn in anticipation of each census being taken, including the 1950 census.

About the 1950 US Census Maps

It’s always important to understand the purpose of a record or source, and the 1950 Enumeration District maps (ED maps) are no exception. Unlike most maps where it’s all about accurately drawing up the current roads and geographical features, census ED maps are drawn up for the purpose of defining boundaries for the purpose of counting people. This means as we look at ED maps we need to keep a few things in mind.

The first thing to understand is that the 1950 ED maps were not necessarily up-to-date with the lay of the land in 1950. Not all streets, parks and features will be included. The reason for this is that the maps themselves were not created for this purpose. Existing maps were used and then enumeration district boundaries were drawn on them.

Maps came from a variety of sources including but not limited to county and City Planning Commissions, 1940 census bureau tract maps, and city engineers. In fact, from a mapping perspective the variety of maps in the collection are fascinating.

Look for the map title, description, legend and census stamps typically found in one of the corners. In this example (see image) from Aurora, Colorado the map used was originally created by the city engineer in 1946 and was revised in 1947.

Following the end of World War II, the United States was growing at a quick pace in 1950. This is particularly true of the newly emerging suburbs. Therefore, if your ancestors built a new home in a new development in 1949, don’t be surprised if you don’t see the street on the 1950 census ED map. However, rest assured that the maps still hold value for your family history as they provide many interesting and unique details about the area surrounding your ancestors’ homes.

Each map was stamped with a small legend where the meaning for each of the colored lines drawn could be indicated. From my random sampling of 1950 census maps across the United States it appears that the coloring coding was consistent as follows:

Red = Township
Green = Corporate Limits/Ward
Orange = Enumeration District

Expect to see errors, inconsistencies and omissions in the maps. The more rural the area the more likely the map was compiled from several sources by the Census Bureau cartographers. This compilation created more opportunity for errors, and often used older maps.

The Meaning of Census Enumeration District Numbers

A census enumeration district number is made up of two numbers separated by a dash. The first number (in this example: 1) represents the county/region. The second number represents the area within the county that could be covered by an individual census enumerator within the amount of time provided for taking the census, about 2-4 weeks. The official start of the 1950 US Federal Census was April 1, 1950.

How to Find 1950 Census Maps

Some 8,000 census maps have been digitized and are available at the National Archives. However, the National Archives website can be challenging to navigate. I recommend using the Unified 1880-1950 Census ED Finder Tool at Steve Morse’s website.

1. Go to https:/stevemorse.org

2. In the menu in the upper left corner hover over US Census and in the secondary menu click Unified 1880-1950 Census ED Finder

3. Select the state from the first drop-down menu.

4. Next select the county.

5. Then select the city.

6. You will then see many enumeration district links listed. In order to find the right one for your ancestor’s home, enter the house number and select the street from the next drop-down menu. Don’t worry about directional parts of the address like west or east unless they are offered in the list of street names.

7. As soon as select the street name, the list of ED numbers should be reduced. In this example we are down to three.

8. To further reduce the possible ED numbers, we can select Cross or back street on same city block. If you’re not sure what the neighboring streets are, click the see Google Map This will plot the address you entered into Google Maps where you can then find the closest cross street, and the next streets over. If the address is not precisely marked on the map, check the address that appears in the Google Maps search box.

In my case, the One-Step tool didn’t allow me to specific W. Arcade, so Google Maps just gave me the general area, and not the address. By adding the W. to the address and pressing enter on my keyboard Google Maps was able to precisely plot the location. Now we can make note of the closest cross street (ex. N. Center), the street north of the address (E. Monterey Ave.) and the street south of the address (W. Noble St.)

9. Head back to the Unified 1880-1950 Census ED Finder page and enter each nearby street (you can enter multiple.) This should reduce the ED numbers one. This is the ED that includes your ancestor’s address.

How to Find 1950 Census Maps

1. Make note of the ED number, and then go back and click the button that says See ED Maps for ____________ County. You could have clicked this button without going through the process of locating the ED number, but the ED number makes it much easier to find your ancestor’s home street on the map. This number will also assist you in being able to find your ancestors in the 1950 census before it is indexed.

2. You will now be on the Viewing 1950 Enumeration District Maps in One Step Re-enter the city from the drop-down menu.

3. Click the Get ED Map Images You will receive two links. The first link is Links to NARA viewer will take you to the page on the National Archives website which includes all of the information about the map and the record hierarchy. Source citation information can be gathered from this page.

5. Click the second link called Direct links to jpegs on NARA server. This will take you to the image by itself as hosted on the National Archives website. I find this the easiest way to save the full resolution image to my computer hard drive. On my PC I right-click on the map and select Save Image As.

This page is also important if you want to use this image in another program such as Google Earth. The URL for this page is the direct URL to the image. Notice that it ends in .jpg. This means that it is the image alone, and this link can be used to create a custom map overlay in Google Earth. You can see an example of a custom map overlay in my video Create a Family History Tour with Google Earth Pro at the 06:13 mark.

Beginning Genealogy – 10 Steps to Success!

by Lisa Cooke | May 19, 2025 | 01 What's New, Beginner, Genealogy Gems Podcast, Video | 2 comments

SHOW NOTES (Video & Audio Podcast): Ever wondered about your family history? Delving into your ancestry can be both exciting and overwhelming. I’m going to break down the basics of genealogy research, offering beginner-friendly tips and tricks to help you get started on your own family tree journey. These tips are also great for getting back to genealogy after taking a break, or if you’ve been at it a while, just making sure that you’ve covered all of the most essential bases.

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.
