I figured it was time to start a thread for the largest metro in west-central Indiana, because why not? The Greater Lafayette metro region is home to about 225,000 people (2021 estimate) and is anchored by two principal cities. Lafayette serves as the largest city and the county seat of Tippecanoe County, while West Lafayette may be most notable as the home of Purdue University. The metro is a hub for automotive manufacturing and related equipment manufacturing. There are some pretty good cultural attractions in the area too. Greater Lafayette is slightly too far away to be considered part of the
Indianapolis metro, and it is geographically shy of the generally defined "
Northern Indiana" region. See those separate threads for projects in those areas.
