TIGER Geocoder Data Dumps

Pre-built PostgreSQL database dumps for the TIGER/Line Rural Address Geocoder.

Available Dumps

File	State	Vintage	Size	Description
`idaho-tiger-2024.dump`	Idaho (ID)	2024	~297 MB	All 44 counties with edges, featnames, places

Quick Start

Instead of downloading and importing raw TIGER/Line shapefiles, restore a pre-built dump:

# 1. Download the dump (from releases)
wget https://git.supported.systems/mctiger/mctiger-data/releases/download/v2024.1/idaho-tiger-2024.dump

# 2. Restore to your PostGIS database
pg_restore -h localhost -U postgres -d tiger_geocoder idaho-tiger-2024.dump

What's Included

Each dump contains:

tiger_edges - Road segments with geometries, names, address ranges
tiger_featnames - Alternate road names and aliases
tiger_places - City/town boundaries with pre-computed centroids
Indexes - GiST spatial indexes and GIN trigram indexes (ready to query)

Creating Your Own Dumps

To create a dump for another state:

# 1. Download TIGER/Line data
tiger-download --state 06  # California

# 2. Import into PostGIS
tiger-import --state 06

# 3. Create dump
pg_dump -Fc -h localhost -U postgres tiger_geocoder > california-tiger-2024.dump

Versioning

Dumps follow the pattern: {state}-tiger-{year}.dump

Year matches the TIGER/Line vintage (e.g., 2024)
New releases are created when Census Bureau publishes updated data (typically annually)
