Frequently Asked Questions

Below are some of the commonly asked questions we get about the income and demographic data we provide.

Yes, we use the most recent income and demographic statistics from the US Census Bureau.

The data comes from the 2019 ACS 5-year estimates. This is data which has been collected in 2015, 2016, 2017, 2018, and 2019 and produces demographic estimates for zip codes/ZCTAs. All income data is inflation adjusted to the latest year, which is currently 2019.

You don't have to take our word for it, here's what the Census Bureau says about the ACS:

  • The American Community Survey (ACS) is on the leading edge of survey design, continuous improvement, and data quality
  • The nation’s most current, reliable, and accessible data source for local statistics on critical planning topics such as age, children, veterans, commuting, education, income, and employment
  • Surveys 3.5 million households and informs over $675 billion of Federal government spending each year
  • Visit 20,000 Group Quarter facilities and sample approximately 194,000 residents each year
  • Covers 35+ topics, supports over 300 evidence-based Federal government uses, and produces 11 billion estimates each year

Every estimate provided in our data also includes a margin of error (MOE). These let data users have a certain degree of confidence in the accuracy of the data. The Census Bureau uses a 90% confidence level.

Example: how many males between the ages of 20 and 24 live in New York?

In this example we can see that the estimate is 663,457 people with a margin of error of 959. This means we have:

  • Lower bound = 663,457 - 959 = 662,498
  • Upper bound = 663,457 + 959 = 664,426

What this tells us is that we can be 90% sure that the true number of males between the ages of 20 and 24 in New York falls between 662,498 and 664,426.

Great question! There are a number of reasons why buying this data is worthwhile for our clients:

  1. It will save you many hours of searching for the correct data on the Census Bureau site.
  2. Once you have the data you then need to organize it into a decent format. We do that for you!
  3. It's usually better to outsource boring tasks if you value your time.
  4. We take care of the data, and you get to focus on putting that data to use.

At the end of the day, most people would rather pay a small sum to get all of the data compiled and formatted to be used with any kind of system you want to use it with.

If you want spend the week checking government documentation, figuring out how to download, clean, merge and format the data into something useable, you definitely can. Most people prefer to pay us to do the hard work, though!

The demographic data we use comes from the US Census Bureau, and they provide the data using Zip Code Tabulation Areas (ZCTAs). ZCTA's are generalized areal representations of the United States Postal Service ZIP Code service areas.

Basically, a ZCTA is similar to a ZIP code, but it represents an entire area, where a ZIP code is just a linear postal route.

Sometimes you'll find there isn't a ZCTA for a certain zip code. These "weird" zip codes are often things like PO Boxes, IRS or post office zip codes. Finally, there are some zip/ZCTAs where there aren't enough samples to produce an estimate.

Bottom line: we use ZCTA and zip coee interchangebly and most people don't know the difference, and don't need to know the difference, in order to use the data to make business decisions.

What you're looking for here is called a ZIP Code to ZCTA Crosswalk. We don't offer that, but you can use this very popular and freely available zip code to ZCTA crosswalk table instead:

Yes, the price is for an annual subscription because the data changes each year when the latest census data is released. You can cancel your subscription at any time though if you do not wish to renew the following year.

We also send an email reminder seven days before your subscription is due to renew, so you can decide at that time if you need the latest dataset.

The current dataset for the 2019 ACS 5-Year has 33,120 ZCTAs. Each ZCTA has more than 200 datapoints available, although a handful of those do have estimates (null) or have estimates of $0.

Since the data we use spans over a trailing 5-year period, the values from previous years need to be adjusted using inflation rates to correctly account for inflation to make them compatible with the latest 2019 amounts for comparison.
