Per a 2020 report by the Congressional Research Service, “The federal government owns roughly 640 million acres, about 28% of the 2.27 billion acres of land in the United States. ... The amount and percentage of federally owned land in each state varies widely, ranging from 0.3% of land (in Connecticut and Iowa) to 80.1% of land (in Nevada). However, federal land ownership is concentrated in Alaska (60.9%) and 11 coterminous western states (45.9%), in contrast with lands in the other states (4.1%). This western concentration has contributed to a higher degree of controversy over federal land ownership and use in that part of the country.”
