Content

When available, the data consists of estimates from the U.S. Census Bureau American Community Survey (ACS) 2017-2021 5-Year Estimates.

Scope of gender :

Please note that American Community Survey asks a question about the respondents current sex, but not about gender, sexual orientation, or sex at birth. The question is intended to capture data for biological sex, not gender. Respondents are supposed to respond with the answer as either of Male or Female. Our research and this dataset mirrors the data reported as Male and Female for gender distribution analysis. No further analysis is done on the data reported from the Census Bureau.

Variables / Data Columns

  • Gender: This column displays the Gender (Male / Female)
  • Population: The population of the gender in the Colorado is shown in this column.
  • % of Total Population: This column displays the percentage distribution of each gender as a proportion of Colorado total population. Please note that the sum of all percentages may not equal one due to rounding of values.
