Just what I read:
Purdue University Airport (IATA: LAF, ICAO: KLAF, FAA LID: LAF) is a public-use airport in Tippecanoe County, Indiana, United States. Owned by Purdue University, the airport is 2 nautical miles (3.7 km; 2.3 mi) southwest of the central business district of Lafayette,[1] in West Lafayette. Because of the heavy traffic generated by Purdue University and its flight programs, Purdue University Airport is one of the busiest airports in Indiana, second only to Indianapolis International Airport.
I guess all those touch and goes mount up, but FAA must not count them...actually a distant 4th take offs
Indy Intl. 4,216,766
Forest Wayne Intl. 360,000 (intl?)
South Bend 329,957
Evansville. 204,352
Lafayette 3084
