# tigris
[](https://github.com/walkerke/tigris/actions/workflows/R-CMD-check.yaml)  
__tigris__ is an R package that allows users to directly download and use TIGER/Line shapefiles () from the US Census Bureau.
To install the package from CRAN, issue the following command in R:
```
install.packages('tigris')
```
Or, get the development version from GitHub:
```
devtools::install_github('walkerke/tigris')
```
__tigris__ functions return [simple features objects](https://r-spatial.github.io/sf/) with a default year of 2024. To get started, choose a function from the table below and use it with a state and/or county if required. You'll get back an sf object for use in your mapping and spatial analysis projects:
```r
library(tigris)
library(ggplot2)
manhattan_roads <- roads("NY", "New York")
ggplot(manhattan_roads) +
geom_sf() +
theme_void()
```
__tigris__ only returns feature geometries for US Census data which default to the coordinate reference system NAD 1983 (EPSG: 4269). For US Census demographic data (optionally pre-joined to tigris geometries), try the [tidycensus package](https://walker-data.com/tidycensus/). For help deciding on an appropriate coordinate reference system for your project, take a look at the [crsuggest package](https://github.com/walkerke/crsuggest).
To learn more about how to use __tigris__, read [Chapter 5 of the book _Analyzing US Census Data: Methods, Maps, and Models in R_](https://walker-data.com/census-r/census-geographic-data-and-applications-in-r.html).
Python users may also be interested in [__pygris__, a Python port of the tigris package](https://walker-data.com/pygris/).

Please note: cartographic boundary files in __tigris__ are not available for 2011 and 2012.
