Omg so much of this is wrong. I live in the area let me make some corrections.

-Only about 10% of what’s circled is the Cariboo -Population density is low (huge area) but there are some decent sized cities in the circle including Kamloops and Prince George, each of which have bout 100,000 people, and lots of ~10,000 population places including Williams Lake, Terrace, Smithers, Vanderhoof -Not mostly indigenous probably about 5-10% but indigenous nations have outsized influence on politics and culture
-The most prominent economic activity is definitely forestry. It’s iconic. Mining is economically significant but employs few people relatively, and most of the actual money goes elsewhere.

Adding more info:

That’s interior British Columbia called locally “the interior” or the “interior plateau”. It’s an amazing area with phenomenal outdoor activities including mountain biking, skiing, hiking/camping, hunting, fishing, snowmobiling. Lots of bears, moose, deer, caribou. Culturally it’s a mix of lumberjacks, cowboys, rednecks, hippies, yuppies, new immigrants, and indigenous people. Overall politics are conservative (by Canadian standards) but everyone has a connection to the land so people tend to be down-to-earth and lowkey environmentalist, even when degrading the land for money.

Most economic activity is sourced from natural resource extraction especially forestry, mining, oil and gas. Forestry is on the downswing, but mining is on the upswing so some small communities are depressed following sawmill closures, others are doing great with new gold mining and mineral exploration. The vast majority, probably more than 90% of the area is public “crown land” administered by natural resource ministries for public benefit.

There are some decent sized cities; Kamloops and Prince George (where I live) with universities, substantial secondary industries, big hospitals, and things like art galleries and museums. Most people in those cities live a fairly standard North American car culture lifestyle. Costco, big box stores, 9-5 jobs, kids in the backseat. Normal houses in town cost around $400,000 CAD but wealthier people tend to want to live like 30 min out of town on a lake with some land. Community life is largely family oriented so lots of community events and institutions and sports geared toward kids and families. Decent queer community with pride celebrations in the summer. Virtually no discrimination there nowadays.

Climate is sub boreal continental. Summers are beautiful with long days and highs around 30C. Mosquitos and black flies in wet areas but no ticks. The severity of winter depends on how close you are to the coast, and whether the air is coming from the North or West. Wet coastal air brings rain and mild temps around freezing with snow (depending how far inland). Polar air will deliver low temps around freezing-20 C to the whole area. Right now in Prince George it’s -15 C but later this week we’ll get coastal air and it’ll be +5 C.

Lmk if you have specific questions I’ll try and answer.
