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 188 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).

Links inside Maryland
These are the site’s strongest pairs nationwide, worked out again using only this state’s counties. The r column shows how closely two measures rise and fall together, from −1 (opposite) to +1 (in step); 0 means no link. A link that shows up nationally but disappears inside every state is really about differences between states. A link that also holds here is not.
These figures are before adjusting for anything. Unlike the national figures, they do not take out population density, income or education.
