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.
Use Google Earth for genealogy to find long-lost family locations on modern maps. Here’s how!
It can be very surprising to discover that you lived somewhere that you never knew you lived. That was the case for Professional genealogist Alvie Davidson, who recently wrote to me. He’d done some fantastic sleuthing on his own recent family history, and discovered that his family had lived in Huntsville, Alabama when he was a toddler. “This is the first I have even known they lived in Madison County, AL.” But he was not sure about how to use Google Earth to help him locate the family addresses he’d discovered.
“I have learned from the U S Government that my parents lived at (three) different addresses in Huntsville, Madison County, AL when I was a toddler in 1944….I never knew we lived in Huntsville but I learned my mother worked for munitions productions during World War II at Redstone Arsenal. She worked several months toward the end of 1944 and had to quit due to onset of pregnancy. We moved to Florida shortly after she left employment at Redstone Arsenal because we show up on the 1945 Florida State Census.”
Alvie sent me three family addresses. Then he asked for some step-by-step help instructions on how to put Google Earth to work to identify their location today.
4 Steps to Revealing More with Google Earth
1. Search each address in Google Earth. Enter the address in the search box in the upper left corner of Google Earth. If you get a hit, mark it with a placemark (clicking the button that looks like a push pin in Google Earth’s toolbar) and name it. In this case I found two of the three street addresses.
2. Locate a map of the area for the appropriate time period. With a little Google searching, I found the 1940 census enumeration map for Huntsville at the National Archives website. Here’s what that map looks like. (Image right) I then went in search of each of the three addresses on the map.
In this case, I conducted a block-by-block search of the 1940 enumeration district map for the missing address: 110 Winston Street. Unfortunately, not all the street names were clearly legible on this particular map, and I was unable to locate it.
3. Overlay and georeference the enumeration district map in Google Earth to compare the past to the present.Georeference just means to match up known landmarks on the historic map with physical locations on the modern-day map, thereby allowing you to match the two maps up together. By so doing, I was able to locate on the enumeration district map the modern-day locations of the two addresses that I found using Google Earth.
There are businesses in both locations today. Below right is a screen shot showing the current location of one of those addresses. Clearly no longer the old family home.
4. Dig deeper for addresses that have changed. As I mentioned previously, I searched for the 110 Winston Street address in Google Earth with no result. If that happens to you, remove the house number and run a second search on the street name alone. Numbers can change, but it is important to verify whether the street still exists today.
In this case, Google Earth did not locate a Winston Street in Huntsville, AL. Knowing that errors and typos can happen to the best of us, I ran a quick Google search for Huntsville, AL city directories, and verified that indeed Winston Street did exist at that time in history. So, at some point between 1940 and today, the name appears to have been changed.
I headed back to Google and ran the following search query:
“winston street” “huntsville alabama”
The quotation marks tell Google that each exact phrase must appear in all search results. The phrases will appear in bold in the snippet descriptions of each result.
The result above caught my eye because it mentions the “Winston Street Branch Library.” Even when street names change, buildings named for those streets often don’t. However, in this case, the website discusses the history of the library, and the Winston Street Elementary School. According to the website, the library “became a part of the Huntsville Public Library (now Huntsville-Madison County Public Library) in 1943. In 1947, the branch was renamed the Dulcina DeBerry Library.” Perhaps the street was renamed at that time as well.
Jumping back into Google Earth I entered “Winston Street Branch Library” in the search box, and was immediately taken to the location, which is just south of the other two known addresses! At this point I would recommend to Alvie, who is a Genealogy Gems Premium Member, to watch my video class Best Websites for Finding Historical Mapsto track down additional maps from the time frame that may have Winston Street clearly marked on the map.
Once I identified this landmark, I then marked the location with a placemark. You can turn off the 1940 enumeration district map overlay by unchecking the box next to it in the Places Panel. Doing this revealed the location on the modern day map. Finally, I headed to the Layers panel and clicked the box next to the “Roads” overlay to reveal the modern day street names.
You can use this technique when you have more success than I did in finding an old address on an old map. Overlay the map, position a placemark on the location, and then turn the overlay off. With one click of the Roads layer you can now see the current street name for the old location you found on the map overlay.
Further digging online did deliver additional maps from the era and area:
We all have locations in our family history that have given way over time to new buildings and parking lots. By using the power of Google Earth, Google search, and historic maps, they don’t have to be lost forever.

Google Earth News
Jennifer in California sent me a fascinating item recently , and she says “Thought you might get a kick out today’s blurb from Google, where they pat themselves on the back for what can be done with Google Earth. No argument from me; it’s amazing!”
So, what can be done with Google Earth besides all the family history projects that I teach here on the podcast and in the Premium videos? Well, Peter Welch and Weekend Wanderers in the UK are using Google Earth to find treasure!
FamilySearch.org, the free and massive genealogy website from the Church of Jesus Christ of Latter-day Saints has added a new way for you to add more memories to your tree.
In addition to photos you can now add audio both at the websiteand the FamilySearch FamilyTree and Memories apps which you can download from your mobile device’s app store.
So now as you’re selecting and uploading family photos to familysearch, you can also gather and record the stories that go with those photos. It’s sort of like being able to write on the back on the photograph, but in an even more personal way.
Your voice, and the voices of your relatives can now be part of your family’s history.
From the FamilySearch website: “Photos and audio attached to deceased ancestors can be viewed by other users on the FamilySearch Family Tree. To protect privacy, photos and audio attached to living people can be seen only by the person who added the memory unless that person shares the memory or album with another user.”
MyHeritage App update
Among the newly introduced features are Family Timelines, the ability to view family trees that you’re matched with, the ability to choose which information you extract from Smart Matches™, an improved research page, and more. Read all about it here
From Craig: “After finding my Paternal grandfather and great-grandfather, I looked for my Paternal GG Grandfather in the same area. No luck. I went to the R.B. Hayes library in Tiffin, Ohio and started looking at every page in the burial listing for the township I thought he would be in. And there he was – last name misspelled! (The “A” was changed to a “K”.) I was able to drive over to the cemetery and located his stone – still readable after his burial in 1885. I plan to go back to the area this summer to look for his wife, who was buried elsewhere (they were separated.) I wish I could get someone to update the lists with the correct spelling, to match the gravestone and census papers, but that seems impossible to do.”
“My brother Ray says we have visited more dead relatives than live ones. Trying now to visit the relatives above ground!”
Spent many hours walking, crawling, pushing through brush brambles and briers just to find and take pictures of tombstones. I regret only one such adventure. If I may. My sweetheart and I went to a small cemetery in New Jersey to gather family names and pictures for Billion Graves and our personal records. While I was taking pictures, my wife was clipping brush and bushes from the stone that identified her families plot.
We had a great day. I filled two clips of pictures and my sweetheart did a magnificent job on that stone. It was only a few hours later, when she started itching that I really “looked” at the pictures and realized that the brush that she cleared from that stone was poison ivy. Wouldn’t have been so bad, but when she found that I’m not affected by poison oak, ivy or sumac. She was not happy.
I have recently started doing ancestry research and have been astounded at what I have found. No creepy tree stories. However, it is nice to know that some ancestors took special care to by buy family plots even though they knew eventually the girls might marry and want to be buried with their husband. I found it interesting that both my grandfather and my grandmother are both buried with their individual parents.
Shirley’s story jogged my memory. My mother died in 1934 when I was 4 years old. She is buried in her father’s plot rather than my paternal grandfather’s plot. I have wondered for years why the burial was arranged that way and imagine all sorts of situations. Were the families feuding? Was one family more financially able to foot the bill. Did my paternal grandfather not like my father? Hmmmm………
I checked out this book from the local library about a month ago. Decided I needed my own copy. All genealogist should read it. It is very informative & entertaining.
About 5 years ago I found the farm on which my gr great grandparents were buried. The tall granite marker with the parents’ names had been knocked over, the foot stones stacked and several large rocks were around the monument and it was in the middle of a field that was being planted and harvested. We made contact with the owner and received permission to have it raised.
In the meantime, I found an obituary for a son who was buried on the family farm. I also found an article about a woman who did dowsing, contacted her and she agreed to come perform the dowsing. I was videoing it when my phone went totally dead! I had never had that happen and it was charged. Thirty minutes later it came back on mysteriously!
She found 2 adult women, 2 adult men and three toddlers. After further search I found another obituary for a grown daughter buried there and 3 toddler grandchildren who died in 1882. She said that the large rocks would have marked the graves. Sadly, they had totally desecrated the family cemetery. But I was excited to learn all I did and was startled by the phone totally dying.
We first talked to Julianne last year in Genealogy Gems Podcast episode 219. In that episode we explored the tragic story of Julianne’s ancestors, the Metthe family. It was a riveting case study of the twists and turns that genealogy can take us on.GEM: Checking in with Julianne Mangin
Julianne had originally been a bit of a reluctant genealogist. But after a 30 year career in library science, including 14 years as a librarian and website developer for the Library of Congress in Washington DC, she could couldn’t help but try to find the truther in the piecemeal stories that she was told by her mother.
Julianne has continued to research and write at her Julianne Mangin blog, and I thought it would fun to check back in with her and see what she’s been up to.
Her latest blog series is called Alice’s Story. It follows the path of discovery she followed to uncover the story of a previously unknown aunt.
The research began where most good genealogical research begins: at the end of Alice’s life and her death certificate.
Institutional Records – But with few records and no first-hand interviews available, Julianne turned to researching the institutions themselves to dig deeper into Alice’s experience. Resource: Genealogy Gems Premium Video: Institutional Records (membership required)
State Census Records can help fill in the gaps between the federal census enumerations. Search for “state census” in the card catalog:
“Copies of many state censuses are on microfilm at the Family History Library. The Family History Library’s most complete collections of state censuses are for Illinois, Iowa, Kansas, Massachusetts, Minnesota, Mississippi, New Jersey, New York, Rhode Island, and Wisconsin. However, censuses exist for the following states also:
