# US Census Data Skill
Query the US Census Bureau API for demographics, population, and economic data.
## When to Use
- "What's the population of Texas?"
- "Show demographic breakdown by county"
- "Get median household income for California"
- "Compare poverty rates across states"
## When NOT to Use
- Non-US data (use world-bank-data)
- Real-time economic data (use financial APIs)
- Historical pre-1790 data
## Setup
Get a free API key at https://api.census.gov/data/key_signup.html
```bash
export CENSUS_API_KEY=your_key_here
```
## API Base
```
https://api.census.gov/data/
```
## Common Commands
### ACS 5-Year Estimates (Most Used)
```bash
# Total population by state
curl -s "https://api.census.gov/data/2022/acs/acs5?get=NAME,B01001_001E&for=state:*&key=$CENSUS_API_KEY"
# Median household income by state
curl -s "https://api.census.gov/data/2022/acs/acs5?get=NAME,B19013_001E&for=state:*&key=$CENSUS_API_KEY"
# Population by county in California (state FIPS=06)
