Explanation:The correct answers are:
- Wyoming; 579,315

There are not many states in the United States of America that have populations that are bellow 2 million, and it is kind of strange that a state has such a low population. The likes of Wyoming (with 579,315 inhabitants), Idaho (1.717 million inhabitants), and New Hampshire (with 1.343 million inhabitants) are one of the very few that have such low populations on their territory. The reasons are multiple, and some of them are the extremely high standard of living, the bad natural conditions, and the size of the states.
