The state’s own figures from 2010 to 2024. A measure published for only one year shows as a single point instead of a line.

The state figure, and the range across its counties
The state figure is the one its own agency publishes. It is never an average of the counties. You cannot average medians (middle values) to get a new median, and a rate has to be worked out again from the added-up counts. The county range next to it shows what a single state number has to hide.
Sometimes fewer counties report than the state has. The missing ones were held back because their counts were too small to publish — mostly deaths. A range from only part of the state is not the state’s full range. It can even sit entirely above or below the state figure. So the number of counties reporting is shown next to it.
You can sort by any column. 47 of these 185 measures have a clear better end, and those are ranked best first. For example, the lowest infant death rate is first place, and so is the highest life expectancy. The rest have no better end, so they are ranked highest first, and the cell says “highest” instead of “best”. A state is not winning or losing by how much of its tax comes from severance taxes (taxes on oil, gas and minerals taken from the ground).

What this state is divided into
9 county-level areas, largest first. Each one is compared with its peers — the counties across the country most like it — not with the rest of this state. 9 of them have no county government — they exist so the whole state can be counted, not to govern.
