The best source of information on the population status of Brown Creeper is the Breeding Bird Survey (BBS). Geographic coverage of the BBS is considered medium for Brown Creeper as it samples less than half of the breeding range, but precision of the trends is high. The Christmas Bird Count (CBC) has similar scores for coverage and precision, but is somewhat less standardized than the BBS. 

The BBS indicates a long-term moderate increase, with steady growth from the 1970s to early 1990s, and a largely stable to slightly declining trend since then. The current population level is estimated to be nearly 50% higher than in 1970. There is some regional variation in trends, with moderate long-term declines in southern British Columbia, contrasting with moderate to large increases in eastern Ontario, Quebec, and the Maritimes. CBC data for Canada also indicate a moderate increase over the long term, but this may in part reflect a northward expansion of the wintering range. At a continental scale, the CBC trend shows little change, but this reflects a mix of Canadian and US birds. Overall, the evidence from the CBC is not strong enough to warrant adjusting the medium level of confidence based on the BBS.

The goal for Brown Creeper is to remain at or above its recent population level, based on the Breeding Bird Survey. Trend data show that Brown Creeper is currently within its goal range.
