This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

|Range Description:||The major breeding range of Barrow's Goldeneye is along the western coast of the USA from southern Alaska to northern California. Breeding colonies are also found in Labrador (Canada), south-west Greenland (to Denmark) and Iceland. Some populations (e.g. Iceland) are sedentary, whereas others undertake longer trips to winter along the Pacific coast of Alaska and Canada, and the north-eastern coast of North America (del Hoyo et al. 1992).|
