Votes Count! 56 Favorite Data Sources for Voter Statistics and Demographics

I’m starting to get requests for voting statistics as custom data pulls for early analyses for redistricting projects. Below is a roundup of my favorite sources of demographic data for voting-related projects. One note: the resources below don’t cover individual voter records. This list below is for voter data for geographic regions like all voters in a congressional district or in a county. Valuable insights start jumping out when you combine these datasets like combining Election Results data with Voter Age Population Demographics from the Census’ American Community Survey.

If you need state-level voting statistics, below is a collection of state agencies with registered voter and election results data. Because we’re often pulling voter demographics, I included notes about any demographic data that we’ve found for voters on the states’ websites in the Types of Data section in the table below.

If you need voting stats for small geographic areas like counties or cities, many counties make voter statistics available on their website. For example, the following breakdown by Party and Language that’s on Alameda County’s website.


2. Voter Age Population Demographics: Census’ American Community Survey

  • Price: Free
  • Geographies: All US Geographies from large like states & counties to small like zips, Census tracts, & block groups

While you can’t get registered voter counts from the Census’ American Community Survey, this dataset has the most current demographics for the voting age population. The most current US Census data is 2017 data, and the 2018 data will be released in December 2019. While you can get American Community Survey demographics for large geographies like congressional districts, you can also get this data for small geographies like zip codes and Census tracts (4,000ish people). These small geographies are particularly helpful if you want to visualize the makeup of a larger geography. You can download this data from and get the following popular demographics.

Age, Sex, Race/Ethnicity

  • Example: voting age population by age and sex

  • Example: voting age population by age, sex and race/ethnicity. In this example, we are displaying Hispanic or Latino but other races & ethnicities are available as well. 


Voting age population by income is tricky, because the income categories are for households (not individuals), and because the Census publishes data for householders under 25 (which kind of makes sense if you think about how few 18 years olds are working jobs but under 25 years doesn’t align nicely to voting ages). But you can get income data by age of householder for the following age breakdowns:

  • Householder under 25 years
  • Householder 25 to 44 years
  • Householder 45 to 64 years
  • Householder 65 years and over

You can get the above data income data by age of householders by race/ethnicity, but I would suggest only getting this data for large geographies like counties because the margins of error will be too large for the small geographies.  Below is a sample of income by age of householder data for a county for the first 2 age brackets. You can also get median income rather than a distribution here. 

There are thousands and thousands of other data points that can be pulled from the American Community Survey (see 2017 ACS Detailed Table Shells), but the ones listed above (age, sex, race/ethnicity and income) are the most popular for voting demographic projects that we’ve done in the past.

When you overlay the above Census tract demographics on top of voting precinct boundaries in a map, you can identify areas with low voter registration. Sometimes, Census tracts and voting precincts line up, so that you can easily compare the Census’ population estimates with the number of registered voters of a precinct. But even when the voting precincts don’t perfectly align with Census tract, we can help you calculate the percent overlap for precincts and Census tracts to estimate the demographics for the precincts. In the map of Miami-Dade County Voting Precincts and Census tracts below, you can see examples of when Census tracts and precinct align and examples of when the boundaries don’t align.

3. Registered Voters: Census’ Current Population Survey

  • Price: Free
  • Geographies: states and metropolitan statistical areas

You can get registered voter data from the US Census using their Current Population Survey dataset. I like to use the Current Population Survey for the total population for cities, counties and states, but you can also use this dataset to get registered voter data for large geographies like metropolitan statistical areas and states. This dataset is the most technically challenging dataset to work with in this list, and here’s what you need to do.

  1. For the raw microdata, go here:
    1. click on CPS Supplement
    2. On the top rows, you will see the Technical Documentation and the microdata files (DOS/Windows preferred).
  2. After downloading, to read in the ascii file, you’ll have to write your own program, using the Record Layout given in the Tech Doc.
    1. An alternative to writing your own program. The NBER site does not have the Nov 2018 file, but does have the Nov 2016.  You may be able to use the data definition statement file for Nov 2016, as there were no changes to the variables or locations.  Certain values, however, did change.   To obtain this data definition statement file, go here: then scroll down to Nov 2016 Voting and Registration.  Select the software of your choice (SAS, SPSS, Stata).  Download the file.  This will convert the ascii file to a SAS/SPSS/Stata file.
  3. Variables you will definitely need to work with are:  GESTFIPS, GTCBSA, PRTAGE, PRPERTYP, PRCITSHP, PES1, PES2.
  4. Be sure to read these parts of the Tech Doc:  Attachments 1, 3, 6, 7, 8.
  5. Main universe for the supplement:   PRTAGE = 18+  and PRCITSHP = 1,2,3,4.
  6. Condition for being registered to vote:   PES1 = 1  OR  PES2 = 1.

4. Election Results (and County Registration & Turnout data): US Election Atlas

  • Price: Depends on the dataset, but I tend to spend at least $200
  • Geographies: All Counties & Congressional Districts in the US

For election results for the entire US, I tend to purchase the 2016 President by County dataset from Dave Leip’s Atlas of US Presidential Elections. Below are some images showing results by state, but county results tend to be more popular. The last time we worked with the Governor Election dataset, there were many states that didn’t have governor election data at the county level.

There’s also voter registration and turnout data by county for the entire US – which sounds interesting, but I haven’t had a chance to work with this data yet. I would like to though. Just waiting for the right project.

5. U.S. Citizen Voting Age Demographics by Age: Social Explorer

  • Price: Free trial, then $100 a month for individuals
  • Geographies: states, counties, cities, census tracts, block groups, congressional districts, state legislative districts

Social Explorer is a web application that lets you pull and map certain datasets. I don’t use Social Explorer often, because we have in-house tools and mapping software that are more flexible. BUT they do have a Citizen Voting Age Population Special Tabulation based on the most current US Census’ American Community Survey. You can get data on:

  • Race
  • Citizens by Race
  • Citizenship status
  • Total Seats in the state
  • District Size Deviation based on different bases
  • Citizen of Voting Age

If you need some of the more popular demographics like voting age population by race or by age and you don’t already know how to pull this data from, you could sign up for a free trial of Social Explorer to see if it’s the right tool for your project. 

6. Custom Data Pull | Cubit

  • Price: Starts at $599
  • Geographies: All US Geographies from large geographics like states & counties to small geographies like zips, Census tracts, & block

Whew! Still reading? I’m impressed.

So if you’ve gotten this far and you’re thinking, “Yeah, sure I could pull all of this data myself in a couple of days, but I have other important things to do and I really don’t want to sift through all of the data dictionaries, methodology statements and tool instructions to make sure that I have the most current data for my area of interest,” you are not alone. You sound just like our other clients at Cubit who depend on us to provide clean, accurate and easy-to-work-with data as well as human-to-human customer support. You can get voting data, as well as hundreds of other data points, in a custom data pull. Prices start at $599 with a 3 business day turnaround. Tell me what data you need for what geography & I’ll get you a free quote & turnaround estimate.

Don’t see the voting stats that you are looking for in the post above? Contact me. I have a couple of other sources that either aren’t as popular or change with too much frequency for me to include in this roundup.

Conversely, do you have a favorite voter statistics resource that isn’t on my list? Please let me know so I can share it with others.

52 Sources of Traffic Counts and AADT Data

Photo by Jake Blucker on Unsplash

Updated: 11/2021. The only time of year that I’m actually happy about traffic is when we get updated traffic data for our reports. Below are 52 of my favorite sources of traffic data that you can use to visualize the AADT or annual average daily traffic that drives past your business (yay!) or past your home (boo!). Let’s start with a table of traffic count data sources from state departments of transportation — DOTs for short.

The DOT datasets above hit the data sleuthing jackpot in that they are free traffic count data sources as well as trustworthy and fairly current. If you have to have 2021 data, skip to the What traffic count data do we use in Cubit’s reports & maps? section below. It can be a bit of pain to incorporate DOT traffic data into your business documents, but it’s nothing that you can’t solve with a good GIS (mapping software) or worst-case scenario, a screen capture tool. 

Need traffic counts for the entire US?

DOT traffic count data are by definition just for 1 state, but some projects require multi-state traffic counts. The Federal Highway Administration provides spatial data for traffic counts for the entire US. The last time I emailed them (November 2021), the shapefiles contained 2019 AADT. I really like the FHWA data, but what I hear from my clients is that there’s a huge learning curve to working with shapefiles. So if you aren’t already familiar with shapefiles, consider sticking with the state DOT resources in the table above or working with us at Cubit to build you a custom map with traffic data.

Don’t have time to learn about AADT, GIS, shapefiles, etc.?

I hear you! Sure, you could pull traffic data yourself. Or for $124, you can get a radius report with traffic data. In fact, our clients order more traffic data reports than any other radius report customization – it’s that popular! Since 2009, these same clients outsource these data pulling tasks and research to us at Cubit so they can focus on building their businesses. 

What traffic count data do we use in Cubit’s reports & maps?

Unlike most of our demographic data that comes directly from government data sources, we use current (2021) traffic estimates from Kalibrate, a private data vendor, first because:

  1. Kalibrate sources their data from public & private data sources. This means that for certain areas, they have more traffic counts than public data sources alone.
  2. Kalibrate’s data are consistent across states. If you need a radius report in New York City where you want to see traffic counts for both New York and New Jersey, your traffic data will be consistent rather than using 2020 New York data versus 2019 New Jersey data.

Second, if the Kalibrate traffic data doesn’t have enough current traffic counts for a particularly rural area, then we double-check with either the federal dataset or the state DOT datasets (above). So you get the best of both worlds – current data from a private data source supplemented by government data.

Since I live in central Texas (Austin to be precise), I’m not surprised to see San Marcos, Georgetown or New Braunfels on the above list. I’m seeing tremendous changes in the smaller cities surrounding Austin, especially as the housing prices & rent rates in Austin are increasing.

Current Census Demographics by DMA

Photo by Chris Lawton on Unsplash

Once in a blue moon, I get a custom data request to use the most current US Census data to produce estimates for Nielsen’s designated market areas or DMAs.

If you can buy data from Nielsen, you should, because they are the only definitive source for DMAs. That said, I’ve tried to purchase data from Nielsen multiple times and they’ve never called or emailed me back. So if you can’t get Nielsen to call you back, you can use the following process.

Nielsen defines “a DMA region is a group of counties that form an exclusive geographic area in which the home market television stations hold a dominance of total hours viewed.”

Given that DMAs are groups of counties and the US Census Bureau publishes estimates for counties, then all you have to do is:

  1. Identify the counties that make up the DMA;
  2. Pull the most current Census demographics for those counties; &
  3. Sum up the estimates.

Easy peasey, right? There are 12 DMAs that split counties. See the map below for 2 examples of DMAs that split counties.

List of DMAs that Split Counties

Oneida County Utica
Lea County Odessa-Midland
Albuquerque-Santa Fe
Apache County Phoenix
Albuquerque-Santa Fe
Kern County Bakersfield
Los Angeles
Riverside County Los Angeles
Palm Springs
Solano County San Francisco- Oakland – San Jose
Sacramento – Stockton – Modesto
El Dorado County Reno
Sacramento – Stockton – Modesto

So if you don’t need data for these problem DMAs, you can google search for a mapping of DMAs to counties (like this one). Then you can pull the most current Census data from (or we sell the most popular demographic data points for all US counties for $199 as an instant download here) and then use a handy SUMIF function in Excel to produce your estimates.

But if you need demographics for all DMAs or at least 1 DMA that splits counties, here’s how you can handle these problem geographies.

1. Produce a shapefile with DMA Boundaries

For the 199 DMAs that play nice with county boundaries

 A. Start with these boundaries:

 B. Fix Rochester, MN and Rochester, NY (which are swapped) and created boundaries for Anchorage, AK, Juneau, AK, Fairbanks, AK and Honolulu, HI (which were missing).

 C. Doublecheck your work using Nielsen documentation and make any needed corrections.

The 11 DMAs that split counties

  1. In the file that you’ve created above, swap the boundaries for these 11 DMAs listed in this blog post above with the boundaries in the 2008 shapefile provided by Harvard here.
  2. Doublecheck your work using Nielsen documentation and make any needed corrections.

2. Intersections with Census geographies.

Now that you have a DMA spatial file that you are happy with, run intersections with Census geographies.

  1. For the 199 DMAs that play nice with counties, produce a county to DMA list.
  2. For the 11 DMAs that split counties, run intersections between the DMA and Census tracts and calculate the area percent overlap. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people.

 3. Estimating Demographics

  1. For the 199 DMAs that play nice with counties, sum the county estimates.
  2. For the 11 DMAs that split counties, multiply the Census tract estimates by the percent overlap. If 10% of the area of a Census tract is in the Reno DMA, then assign 10% of the population in that Census tract to the Reno DMA. Thoughts: there are more accurate ways to solve this, but this one works pretty well for the level of effort involved.
  3. You can use this formula for median calculations like median income or median age.

4. QA

  1. Compared your results to Nielsen’s data. For example, New York, Los Angeles, & Chicago are the DMAs with the largest populations. Are your 3 largest DMAs also New York, Los Angeles & Chicago?
  2. Consider calculating a percent difference between Nielsen’s Metro age 12+ population for 2019 and the Census Bureau’s 2018 age 10+ population. This percent difference would show you if any of your estimates are off.

Unsurprising: Texas and Florida
As a Central Texan who lives near to Hays, Comal & Williamson Counties, I’m not surprised to see these 3 counties in the top 20 fastest growing list. With solid job opportunities and a reasonable cost of living, continued population growth in Texas is likely.

As for Florida, I’d be interested to pull age data for the new residents. Is this Florida population growth due to Baby Boomer retirees, or are families and young couples moving there in search of job opportunities?

Surprising: North Dakota and Where’s California?
With 2 North Dakota counties at the top of the fastest 100 growing counties list, it appears that the North Dakota oil boom continued to attract workers through 2014. And surprisingly, no California counties appear in the top 20 list this year.
