Colorado Census Block Group Demographics and Population by Age, 2023

Colorado census block groups contain American Community Survey data for 2023, aggregated by the Department of Local Affairs. The dataset includes population counts, race and ethnicity breakdowns, and detailed age group distributions. Data is provided in multiple formats including CSV, JSON, and XML.

Use Cases

• Analyzing racial and ethnic composition across neighborhoods using columns like `hispanic`, `white_nh`, `black_nh`, and `asian_nh`.
• Modeling age distribution for service planning using age group columns from `ageless5` to `age75_79`.
• Mapping population density and demographic clusters by joining `the_geom` (geometry) with population count columns like `pop`, `male`, and `female`.

Strengths

• Includes detailed demographic breakdowns for over 20 specific age groups and 7 race/ethnicity categories.
• Geographic data (`the_geom`) enables spatial analysis and mapping of census block groups.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
