Median Household Income

The median income for a group is that amount above which half the group has more and below which half the group has less. It is “in the middle.”

According to the U.S. Census:

Family. A family is a group of two people or more (one of whom is the householder) related by birth, marriage, or adoption and residing together; all such people (including related subfamily members) are considered as members of one family. See median family income.

Household. A household consists of all the people who occupy a housing unit. A house, an apartment or other group of rooms, or a single room, is regarded as a housing unit when it is occupied or intended for occupancy as separate living quarters; that is, when the occupants do not live and eat with any other persons in the structure and there is direct access from the outside or through a common hall.

A household includes the related family members and all the unrelated people, if any, such as lodgers, foster children, wards, or employees who share the housing unit. A person living alone in a housing unit, or a group of unrelated people sharing a housing unit such as partners or roomers, is also counted as a household.

From 1984 through 2009, Maine’s household income was always less than that of the United States as a whole.  Half of these years (the median) the difference was more than 6.4%. More Economic Data
