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.
Family History: Genealogy Made EasyPodcast with Lisa Louise Cooke Republished June 24, 2014
Listen to the Family History: Genealogy Made Easy podcast by Lisa Louise Cooke. It’s a great series for learning the research ropes and well as refreshing your skills.
Welcome to this step-by-step series for beginning genealogists—and more experienced ones who want to brush up or learn something new. I first ran this series in 2008-09. So many people have asked about it, I’m bringing it back in weekly segments.
Episode 37: Your Genealogy Questions Answered, Part 2
Today’s show is all about YOU! Just like Episode 36, this episode is made up completely of your emailed questions, comments and stories. Joining me on today’s episode to read your emails again is my daughter, Lacey Cooke.
Question: Is there a way to get iTunes to download all of the podcasts instead of just the most recent ones? I thought I saw it on the website somewhere but now I can’t find it. –Melanie Armstrong
Answer: (updated since the podcast originally aired): In your iTunes LIBRARY, on the line where the Genealogy Gems Podcast is listed click the GET ALL button. This will download all the past episodes to iTunes on your computer, to be listened to at your convenience. Downloading will take several minutes. You will see a little spinning orange circle to the left of the podcast name as it downloads. Once the episode is downloaded the text will turn from gray to black. Double click the episode and it will start to play after a moment or two.
Answer: I love all those free forms at Family Tree Magazine! I’ll tell you the truth, I decided to throw mine away. I transcribed everything into my database and threw away the paper. Everything is properly sourced there, which is key. I avoid duplicating efforts, which has happened to me when looking back at old paper forms. If I need to double-check things, I do it from the actual sources—the birth or death certificate or interview—not from the family group sheet. The only exception is if the group sheet is part of a brick wall case file that I haven’t solved yet. I keep them until the case is solved, and then the cited answers go into the database.
Question: How do you know when records/indices are complete? I have been looking for immigration records for my family and cannot find them.
They came in large family groups, so you would think it would be easy to find. Even though the name (Mauge) is often misspelled (Mange, Mauga) I cannot find them at Ellis Island, Steve Morse’s website, The National Archives or through my Ancestry.com subscription. The years span 1880 through 1885. Are these immigration records complete or am I looking in the wrong place? -Anne-Marie Eischen
Answer: There are many factors involved here, and many avenues to pursue. Based on other information you told me about your family’s arrival, here are some ideas:
The Family History Library has microfilm of the Baltimore Passenger lists between 1920 and 1897 – and it lists the main author as the U.S. Dept of the Treasury, Bureau of Customs. Passengers are indexed by soundex and the soundex code for Mauge would be M200. But considering the variations you have found of the name you’ll want to arm yourself with the soundex codes for all those variations. The M200 names are on Film # 417302 which I found in the Family History Library catalog and familysearch.org and you can just go to your closes Family History Center and order the film for under $10 and they will send it to you to view at the center.
Click here for a great summary of Baltimore passenger lists by Joe Beine online.
You will also find an index for Baltimore passenger lists between 1820 and 1897 at the Allen County Public Library in Fort Wayne, IN.
Look closely at your source for the port information, and see if you can locate any other verification of that. Maybe she actually arrived through another port.
Usually I would tell you to check departure lists, but in this case, departure lists for Bremen for that time period are not available.
Question: I wanted to share the results of my Google Alerts. My father had red hair and was called “Red” most of his life. So when I ask for “Red” Browning in my alerts, I have received information on the red Browning sweater (the Browning clothing line), a red Browning rifle case (they make guns) and recently the Cincinnati Reds Tom Browning went to jail (the Red’s Browning…). Alas, nothing yet on my Dad! Another family name is Gorry – you can imagine what I got last Halloween! I do love the alerts though – and have added eBay alerts too, thanks to you. Keep encouraging us and thanks for the great tips! -Joan Ketterman
Answer: I’m not sure how much I can help with that one – keep playing with the “plus” and “minus” signs in your searches to refine what you’re looking for. And I’m glad you’re using those eBay alerts. Learn more about eBay alerts in Genealogy Gems Podcast Episode 140. Note: Genealogy Gems Premium Members can learn more about Google Alerts in Premium Podcast Episode 28.
Comment: On the podcast you recommended using Google Books. I have a “gem” for you….I have a link where the LDS church has archived loads of family history books: http://www.familyhistoryarchive.byu.edu. Follow the link and type in the surname of your choice. I have found some wonderful stories there about my ancestors. – Susan in West Palm Beach Florida
Note: The BYU Family History Archive she references has migrated into the Family History (Digital) Books collection at FamilySearch along with the digital book collections of other repositories/ They are now searchable at FamilySearch.org.
Question: This is just something that bugs me. WHICH is the correct pronunciation of Genealogy??? GEEN-e-alogy (with a long “e” at the beginning) or Gen-e-ology (with a short “e” at the beginning)?
Answer: I’ve heard it both ways and I’ve pronounced it both ways. But when I went to Dictionary.com, they actually have an audio pronunciation and they say, GEEN-e-alogy, with a long “e” at the beginning. However you pronounce it, it’s a barrel of fun!
Question: How can I learn more about the Freedom of Information Act?
Question: Hello, I just finished listening to the June Family Tree Magazine Podcast. I have been wanting to write to you for months now to ask you this question: Who is the musician playing the guitar music during the podcast? My husband is a big Chet Atkins fan and I thought it could be Chet but my husband says no just from listening to it. Can you please provide me with the musicians name? -Melissa Roberge
Barry Landau Sentenced to 7 Years for Thefts From National Archives, Other Institutions
Washington, DC . . . U.S. District Judge Catherine C. Blake yesterday sentenced Barry H. Landau to seven years in prison, and three years of supervised release, for conspiracy and theft of historical documents from cultural institutions in four states, including the Franklin D. Roosevelt Presidential Library in Hyde Park, New York.
The items stolen from the Roosevelt Library, which is part of the National Archives and Records Administration, were seven “reading copies” of speeches that Roosevelt delivered. They contained his edits and handwritten additions, along with his signature. They have all been recovered.
Landau’s co-conspirator, Jason Savedoff, will be sentenced at a later date.
Archivist of the United States David S. Ferriero said he was pleased that Judge Blake “recognized the seriousness of this crime and meted out an appropriate punishment that will serve as a warning to others who may contemplate stealing our nation’s history.”
“There is a very special bond that forms between researchers and research institutions. It’s kind of like an insider’s club. We speak the same language, share the same interests, explore the same minute details of historical knowledge that will eventually fill in the fabric of our shared history as a nation,” the Archivist added.
“When a researcher turns out to be a thief and steals the documents that are the very underpinnings of our democracy, our trust and respect for the community is shaken. Barry Landau is just that thief. Dressed in the guise of a scholar, he ingratiated himself with our staff and stole priceless documents from the Franklin Roosevelt Library. In essence he robbed from all of us—our collective history. And he did far worse damage to numerous other research institutions around the country.”
The Archivist said that because of incidents such as those involving Landau, the National Archives and other research institutions around the world have become more vigilant over the last few decades. They have instituted a number of measures aimed at preventing theft, such as closed-circuit cameras, clean research room rules, exit searches, and increased staff surveillance.
“When a theft does occur, we rely on the Office of the Inspector General and the Justice Department to build a case and bring the perpetrator to justice,” he added. “I want to thank them for their hard work.”
Lynn Bassanese, Acting Director of the Roosevelt Library, recalled that when Roosevelt dedicated his library on June 30, 1941, he declared it an “act of faith” in the American people.
“Barry Landau and Jason Savedoff violated that faith by taking advantage of the trust and confidence that the Roosevelt Library’s staff has for its researchers,” she said.”With the successful return of the stolen documents, the Roosevelt Library renews its commitment to protect and preserve the records of the Roosevelt Presidency and to make them accessible to the American people for generations to come.”
According to Landau’s plea agreement, the “reading copies” of Roosevelt’s speeches were stolen when he and Savedoff visited the Roosevelt Library on December 2, 2010.
“Reading copies” are the actual copies of the speeches from which the President read. They contain edits and handwritten additions made by him and bear his signature.
Four of these “reading copies” of speeches were sold by Landau on December 20, 2010, to a collector for $35,000. Three other “reading copies” of inaugural addresses delivered by Roosevelt, valued at more than $100,000 each, were recovered from Landau’s apartment in New York City during court-authorized searches, including the water-stained reading copy of the inaugural address Roosevelt delivered in a steady rain in 1937.
Judge Blake also ordered Landau to pay restitution totaling $46,525 to three dealers who purchased the stolen documents from Landau, not knowing they were stolen. She also ordered Landau to forfeit all the documents recovered during searches of his New York apartment.
The National Archives and Records Administration is an independent Federal agency that preserves and shares with the public records that trace the story of our nation, government, and the American people.
If you have immigrant ancestors who arrived in the U.S in the 1900s, these 7 sources can help you track their journey—perhaps even to that overseas hometown, so crucial to your genealogy success! (Thanks to Legacy Tree Genealogists for providing us with this guest...
