The building codes are mostly locally drawn up and enforced. The US is so big that required R values for construction can vary greatly. In the southern US the highest recommended R values are the lowest recommended values for the northern regions.

A friend moved from Minnesota to Florida where he built a house. He mentioned how much less insulation was put in the new Florida house than was in his old place in Minnesota. He said it was a cost savings measure. Plus in Florida they are only cooling the house (or on rare occasions heating it) by 20 or so degrees F (~10C). Whereas in Minnesota you're heating the house 50-60 degrees F or more during the winter. This was in the 90s. Times have changed so I would expect that now his story might be different.

R value is the thickness of the insulation divided by the thermal conductivity of the material. (That's a simplistic definition. It's actually a fairly complex calculation.) It's basically a measure of the resistance to heat transfer. The typical recommended R values (now) are:
Ceilings/attics are R30-50 in the south, R50-60 in the north.
Walls are ~R14 everywhere.
Floors are R13-19 in the south, R25-30 in the north.
The central US is somewhat in between these numbers, but tend to go as high as in the north.

The current recommendations/requirements are all fairly new now that climate change is starting to cause regulation and the cost of heating and cooling are going up. There are a lot of older houses that don't even come close to current recommendations. In a lot of places, especially rural, it'll still come down to est. cost to heat vs cost of insulating rather than some regulation. Northern MN has lots of trees, you see a lot of wood burning. Southern MN has lots of corn you see more corn pellet burners. These are typically used to offset the cost of oil or gas heating and are easier and cheaper to add than insulation on older construction.

The house I grew up in (northern Minnesota) was a drafty cold house in the winter - built in the 50s. You could feel a breeze come in some outlets. But, heating was cheap back then. You just upped the thermostat and/or wore a sweater. You also got used to it. My brother now lives in the old place and keeps the thermostat set to 67 and you dress up if it feels cold. He typically wears shorts and a t-shirt around the house - as I said, you get used to it.
