(2) separated or divorced, which includes married persons who are legally separated and those who are not living together because of marital discord;
(3) widowed; and

(1) a city has a population of at least 50,000;
(2) the Census Bureau defines an urbanized area of at least 50,000 people with a total metropolitan population of at least 100,000 (or 75,000 in New England). The Census Bureau's definition of urbanized areas, data on commuting to work, and the strength of the economic and social ties between the surrounding counties and the central city determine which counties not containing a main city are included in an MSA. For New England, MSA's are determined by a core area and related cities and towns, not counties. A metropolitan statistical area may contain more than one city of 50,000 and may cross State lines.
(1) owned, which includes dwellings that are mortgaged, and
(2) rented, which includes rent-free quarters belonging to a party other than the occupants, and situations where rental payments are in kind or services.
