A Julia package for retrieving data from the U.S. Census Bureau’s American Community Survey (ACS) API. This is based on the R `tidycensus` package by Kyle Walker ([GitHub - walkerke/tidycensus: Load US Census boundary and attribute data as 'tidyverse' and 'sf'-ready data frames in R](https://github.com/walkerke/tidycensus/tree/master)). This replaces the unregistered ACS.jl package previously announced. (The name was too short to meet current conventions.)

## Features

- Fetch data from 1-year, 3-year, and 5-year ACS estimates
- Support for various geographic levels (state, county, tract, block group)
- Automatic handling of state FIPS codes
- Robust error handling and retries
- Returns data in DataFrame format
- Separate functions for estimates and margin of error values
- Fetch the list of available variables
- Download 2023 state and county 500k shapefiles
