List of counties with no Non-Hispanic Native American Population in Colorado

According to data from the United States Census Bureau, the following counties in Colorado have no recorded Non-Hispanic Native American population*:
  • Washington County
  • Phillips County
  • Ouray County
* These counties were not included in the ranking above, as they do not meet the population criteria. It is possible that a small population exists but was not reported or captured due to limitations or variations in Census data collection and reporting.

Methodology

This ranking list is based on data from the American Community Survey (ACS) 5-Year Estimates, conducted by the U.S. Census Bureau. The ACS is one of the most reliable sources for understanding population trends across different locations, and it provides estimates for various racial and ethnic groups at city, county, state and all geography levels down to the Census block group.
This list ranks counties in Colorado by their Non-Hispanic American Indian and Alaska Native (AIAN) population, using the most recent ACS data available.

How the Census Defines Non-Hispanic Native American Population

The U.S. Census Bureau allows people to self-identify their race, meaning individuals can choose one or more racial categories when responding to the survey. In this ranking, we include everyone who identifies as Non-Hispanic Native American, whether alone or in combination with another race.
Here are a few important things to know about how race is reported:
  • Some people identify as Non-Hispanic Native American alone, while others identify as Non-Hispanic Native American along with another race (such as Non-Hispanic Native American and White).
  • Hispanic / Latino origin is reported separately from race, so someone can be both Hispanic and Non-Hispanic Native American .
  • We’ve used the “Non-Hispanic Native American alone or in combination” category unless noted otherwise, which gives a broader picture of the Non-Hispanic Native American population in each area.

How We Ranked the Data

This ranking is based on the total number of people who identified as Non-Hispanic Native American alone or in combination in counties. To provide additional context, we’ve also included two key percentages:
  1. % of Total County Population – This shows what percentage of the total state population identifies as Non-Hispanic Native American .
  2. % of Total Colorado Non-Hispanic Native American Population – This tells us how much of the entire U.S. Non-Hispanic Native American population lives in that state.
To keep things simple, all population numbers have been rounded to the nearest whole number, and percentages are rounded to one decimal place. Because of rounding, some percentages may not add up to exactly 100%.

Things to Keep in Mind

Like all survey-based data, ACS estimates come with some limitations. Here are a few things to be aware of:
  • In places with very small Non-Hispanic Native American populations, the numbers may not be reported at all due to privacy protections or sampling variability in the survey.
  • Since the ACS is based on a sample, the numbers are estimates, not exact counts. That means they may slightly differ from other sources like the decennial U.S. Census.
  • Counties that don’t have any reported Non-Hispanic Native American population are not included in the ranking but are listed separately below for reference.
This ranking is meant to provide a clear, data-driven look at where Non-Hispanic Native American populations are most concentrated while keeping the numbers easy to understand.
