1950 US Census Maps – How to Find and Use Them

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.

Which Genealogy Website Should I Use? Comparing the Genealogy Giants.

Genealogy Giants quick reference guide cheat sheet Big 4

“Which big genealogy website should I use?” Genealogy Gems takes on that ambitious family history question in ongoing comparative coverage of the “Genealogy Giants,” Ancestry.com, FamilySearch.org, Findmypast.com and MyHeritage.com. (Disclosure: this article contains affiliate links. we will be compensated if you make a purchase. Thank you for supporting this free blog.)

Which Genealogy Giants website is best for me?

The four Genealogy Giants (Ancestry.com, FamilySearch.org, Findmypast.com and MyHeritage.com) all offer the following to their top-tier users:

  • millions of historical records from around the world;
  • powerful, flexible search interfaces;
  • family tree-building tools;
  • automated record hinting (if you have a tree on the site);
  • Help/tutorials for site users.

But each has unique strengths and weaknesses, too. You may determine that one or two of these sites meets your needs now. But your family history research needs may change. For example, you may discover an Irish or Swedish ancestor whose records may be hosted on a different site than the one you’ve been using. Or you may find that you need DNA to push back further on your family tree. It’s critical to which sites offer what records and tools, so you know your options when your needs or interests change.

Comparing the Top Genealogy Websites

There are so many features on each site–and an apples-to-apples comparison isn’t easy.

Here’s one example: how many records are on each site? Some sites include DNA results and user-submitted family tree profiles in their total record count. Others don’t. One site has a universal family tree–ideally with one record per person who has ever lived–and the others host individual trees for each user, leading to lots of duplication. Does a birth record count as one record? FamilySearch thinks so. But other sites may count a birth record as three records, because a baby, mom and dad are all named. So it’s not easy to compare historical record content across all the sites.

Reviews of “Genealogy Giants”

“You may have asked, ‘Which is the best online genealogy service for me to use?’….I suspect this video [presentation by Sunny Morton at RootsTech 2017] will answer most of your questions. Topics covered include cost, record types, geographic coverage, genetic testing, DNA matching, search flexibility, languages supported, mobile-friendly, automated matching, and a lot more. Sunny provides the most information about these four sites that I have ever seen in any other one document or video. This is a keeper! I have been using all four of these web sites for years and yet I learned several new facts about them, thanks to Sunny’s online video presentation. I suspect you will learn some things as well.”  – Dick Eastman, Eastman’s Online Genealogy Newsletter

“We want to tell you how much we enjoyed the presentation about the comparison of the four major websites. [Sunny] did an excellent job and we were so thrilled with her presentation. She was so prepared and presented it in such a manner as to be understood. Give her our best.” – Eldon and Dorothy Walker

“I am incredibly thankful for your Big 4 session. I’ve never had interest in Findmypast or MyHeritage as I felt FamilySearch and Ancestry had it all…and hadn’t heard of PERSI either. With newly found Irish roots (via DNA), I’m excited to extend some lines that have gone cold.” – a FamilySearch employee

Google Earth for Genealogy: How to Identify Old Photos’ Locations

google searchDo you have old pictures but aren’t sure where they were taken? Sometimes Google Earth has the answer. Check out this question from podcast listener Dennis:

Q: “I am scanning slides from my only trip to my ancestor’s home in rural Germany and don’t recall the names or locations of a few people. The clue hear is ‘slides’. They were taken in 1986! I have a question regarding something I thought I heard on one of your podcasts regarding identifying a building via a picture that is uploaded to a web site. Can you give me some help with this?”

A: Yes! On my website, I offer a FREE video in which I demonstrate how to identify a building in an old photo using Google Earth. You can watch the free video by going to www.GenealogyGems.com, hover your mouse over VIDEO, and click on Google Earth for Genealogy in the drop down menu.

Another option is to use the free Google app on your smart phone or tablet. Open the app, tap in the search box, tap the Camera icon, and take a photo of the photo you have that contains the building you want to identify. (This works best with more well known locations.) It’s a long shot, but you never know – Google just may be able to identify it.

Google Earth for Genealogy BundleGood luck, Dennis–and all the rest of you out there who are puzzling over how to identify old photos’ locations.
