The 10-year migration count trends for the Broad-winged Hawk suggest a mostly stable population trend across North America as 44% of 78 sites reported no significant change in counts while 19% showing declines. Counts with highest annual counts are near the Great Lakes and in the Gulf Region where most sites observed stable numbers. Cardel, Veracruz, has the highest average count of Broad-winged Hawks for the 10-year period, and has reported a stable count trend.

The Broad-winged Hawk primarily overwinters in Central and South America and is not well represented on winter surveys such as the Christmas Bird Count (CBC), except in several southern states. A small number of Broad-winged Hawks winter in the United States, however data from the CBC suggest the number may be increasing. For instance, CBC data from Texas indicates a 4.79% annual increase in hawk abundance from 2009-2021. The Broad-winged Hawk is listed by the IUCN Red List as a Species of Least Concern, however, the species is currently listed as a Species of Conservation Need in 14 states, primarily in the East. Contrasting with this pattern, the western populations seem to be increasing, along with Canadian populations, as indicated by 10-year abundance data from eBird (increases of 24.3% annually from 2012-2022).

Broad-winged Hawks utilize large forests for nesting and wintering and are sensitive to forest fragmentation. Regional declines of eastern populations appear to be occurring in areas undergoing extensive suburban sprawl where forest fragmentation may dominate. Deforestation of tropical forests may be a current threat to the species as well. Broad-winged Hawks continue to be threatened by shooting and illegal trapping in Central and South America. Mortality due to vehicle collisions is also frequently reported. Little is known about disease and contaminants threats although West Nile Virus has been found in dead birds in recent years.
