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.

INTERVIEW: ANGELA WALTON-RAJI
Angela Walton-Raji instructs the African-American Genealogy Research Essentials webinar.
Angela’s oral history questions: What to ask your elders
Did they happen to know anyone who had been born a slave when they were a child?
Who was the oldest person that you remember when you were a child? And did that person ever talk about anyone who may have been enslaved?
What do you know about where the family was from? (Were we always from Georgia, or, were we always from Pennsylvania, or was there a time when we came from another place? (Read more about the Great Migration she mentioned.) Why did we move? Who remembers that journey?
Were people involved in the Civil Rights movement, in the Garvey era, with the Freedom Riders, or other important events in their lifetime? What kinds of things did they see?
Who in the family participated in the military (in World War II, I, the Spanish-American War)? African-American military units through the mid-20th century were still referred to as Buffalo soldiers. (She mentioned the Triple Nickel, a unit of all-black World War II paratroopers.

EXPERT TIP ON FINDING ANCESTORS “MISSING” IN CENSUSES
Read their Q&A: Kate Eakman takes on a Gems listener question from someone who has already done a lot of work trying to locate a relative in the 1940 U.S. census

There is no doubt that this is an exciting time to be a genealogist. Here at Genealogy Gems, we are announcing new record collections online every month, advances in genealogy databases and their ability to retrieve the information we are looking for, and of course, DNA testing. There really has been no time in history where such a wealth of information about our past has been so readily available to so many.
In another ground-breaking development in the DNA world has been a recent publication in a scientific journal by the scientific team at AnccestryDNA. It is titled, “Clustering of 770,000 genomes reveals post-colonial population structure of North America.” Or, in more understandable terms, “Your DNA can tell us where you came from in America in the last 500 years.”
Wow, right? So how did they do this?
Well, the power really is in the numbers. In this particular paper they used 770,000 people, but now that they are approaching having testing 4 million people, you can bet the same principles will be applied to a larger data set and we will see even more as a result. But even though it takes a large data set to accomplish this, it really all still comes down to the relationship of two people.
To start, Ancestry determines how just two people are genetically related. Then they find how those two are related to a third, again, looking only at pairs of people. This goes on and on and on until everyone in the group as been compared. Then we use a graph to plot those relationships, with those more closely related clustering around each other. Then the real key, the point where we see the marriage of genetics and genealogy: they add in the family history information for each of these individuals in the cluster. What they found was astounding. They have displayed the data in Figure 3 in the paper:
Distribution of ancestral birth locations in North America. Summary map from Nature Communications; click to see article with full explanation of map data. Image used with permission of Ancestry.com.
It is a map of the United States with colored dots scattered across the landscape. The location of the dots corresponds to the genealogy of those tested, while the color of the dots relates to their genetic clustering. Those who clustered closest together are the same color. The result is a nearly perfect rainbow, with each color holding its respective spot on the map, with very little overlap between groups. (There are actually two maps in the paper, just to make things easier to see.)
We might be tempted when looking at the maps to think, oh, well, of course there is a large population of European Jews in New York, everyone knows that, no breakthrough there. But it IS!! This isn’t their family history, or their accent or their culture that is telling us this, it is their genetics!
As if that wasn’t exciting enough, further on in the paper they describe how we can trace migration patterns of different groups over just a few generations. In the paper they specifically mention French Canadians and Cajuns/Acadians, but this same principle can theoretically be applied to dozens of other groups.
For example, let’s say you have an ancestor in Texas about 4 generations ago, but you aren’t sure where she came from. If technology like what is published in this paper ever reaches your testing company, your DNA could tell you that you fit into the Lower South group, meaning that your ancestor likely hails from, well, the South!
This is just a glimpse into what the advances in genetics are bringing to your genealogy toolbox. So hang on to your hats, and keep tuned in here at Genealogy Gems for all of the latest updates.
It’s the summer of 1938, and wealthy young socialite Miss Layla Beck is now on the dole as a WPA worker, assigned to write a history of the small town of Macedonia, West Virginia. As she starts asking questions about the town’s past, she is drawn into the secrets of the family she’s staying with and drawn to a certain handsome member of that family. She and two of those family members take turns narrating the story from different points of view, exploring the theme that historical truth, like beauty, is often in the eye of the beholder.
Annie Barrows is also the co-author of The Guernsey Literary and Potato Peel Pie Society. This novel takes place after World War II in a London recovering from the Blitz and an island recovering from German occupation. At the heart of Guernsey is an unlikely love story and the inspiring tale of a community that took care of each other in their darkest days with humor, compassion and good books.
