title: Great Lakes Angler Population Estimates by Age and Sex in Five U.S. States, 1999-2016
title: Version 1

description: This collection includes estimates of the number of in-state resident recreational anglers from the states of Illinois, Indiana, Michigan, Minnesota, and Wisconsin. It also includes estimates of the smaller subset of anglers who fished the Upper Great Lakes (Lake Superior, Lake Michigan, or Lake Huron) or their tributaries for salmon/trout by state of residence and separately by lake fished. All estimates were broken down by year, single year of age, and sex.
description: To facilitate investigations into angler demographics among the five Upper Great Lakes states.
description: Individuals who purchase any type of fishing license are counted as "anglers" by their state of residence. Estimates of the number of unique individuals who fish the Great Lakes and their tributaries, up to the first barrier, for salmon or trout are noted as "Great Lakes salmon/trout anglers" and are counted by both state of residence and by lake fished. The datasets include only in-state resident anglers; out-of-state residents are excluded. In some instances, the state Department of Natural Resources provided data that was already filtered by residency. When necessary, in-state residency was determined based on license type sold or zip code of residence. For the state of Michigan, a small number of observations (approximately 0.28 percent of records) were missing information that could be used to determine residency status, and these individuals were removed from the data.
description: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
