Reading the Chart:

The entries under the Percent of total households headings are percentages. The "Family households Total" and "Nonfamily households Total" percentages add up to approximately 100%. The subheadings underneath do not add up to 100%, because they do not include all the types of households. For example, there is no subheading for "Male householder, no wife present.". The colored bars fill the cells in proportion to the percentage value.

The entries under the Average population per- heading are averages of the number of people in each family or household. Here the colored bars indicate a percentage of an arbitrary maximum (5). For example, the colored bar for an average family size of 2.5 fills half of the table cell.

Total Households counts households, not people. Here the colored bars represent percentages of the highest household count of any county in the state. For example, the county with the most households will have a colored bar that fills the cell. A county with half that many households will have a colored bar that fills half the cell. For small percentages the bar does not appear.

Census Department definitions:

A household includes all of the people who occupy a housing unit. A housing unit is a house, an apartment, a mobile home, a group of rooms, or a single room occupied (or if vacant, intended for occupancy) as separate living quarters.
A family includes a householder and one or more other people living in the same household who are related to the householder by birth, marriage, or adoption.

Abbreviations used in location names: Co.=County, C.A.=Census Area, Pa.=Parish, Mu.=Municipio.
