It is the province's smallest, most rural and least-populated county. Kings County is also least dependent upon the agriculture industry compared with the other two counties, while being more heavily dependent on the fishery and forest industry. Comparatively large parts of the county are still forested and it hosts the province's largest sawmill. The only heavy industry, aside from forestry and industrial farming, is a small shipyard, although secondary manufacturing has been established in recent years.
In 2008, Kings County was the region with the second highest self-reported obesity rate in Canada.
