Growing up in Rural Iowa, And spending much of my life in Rural Iowa. I can say the top one is what most of the state looks like, with the added hog confinement every mile or so.
The second picture is not an accurate representation of rural Iowa. While there are some houses etc that look something like that, it is not an accurate representation of rural Iowa, and would probably be more accurate of some of the poorer neighborhoods of the larger towns and cities in Iowa and especially of other states, than rural Iowa. This type of house is more like 1 in 1000 in rural Iowa, if that. Venture out and drive around rural areas and towns you wont see that many run down shacks, especially compared to other states and areas.
There might be old homes, and there might be some that need some upkeep or updating, but not many of this level. Meth is bad, but from what I have seen most of the methed out people aren't living in a house, here, they are living in rent controlled and subsidized apartments, otherwise property and rent is too expensive everywhere. Land is breaking records, so any old house is getting torn down because the land is worth more than the house. In towns rent on a house is higher than the rent controlled apts. so those spending every dime on meth are living in the local low income apts. While regular rent in houses and apts is skyrocketing even in rural areas.
