When information is missing or inconsistent, the Census Bureau uses a method called imputation to assign values. Imputation relies on the statistical principle of "homogeneity," or the tendency of households within a small geographic area to be similar in most characteristics. For example, the value of "rented" is likely to be imputed for a housing unit not reporting on owner/renter status in a neighborhood with multiunits or apartments where other respondents reported "rented" on the census questionnaire. In past censuses, when the occupancy status or the number of residents was not known for a housing unit, this information was imputed.
An operation which allows respondents to use the Census Bureau's Internet site to (1) ask questions and receive answers about the census form, job opportunities, or the purpose of the census and (2) provide responses to the short form.
Interpolation frequently is used in calculating medians or quartiles based on interval data and in approximating standard errors from tables. Linear interpolation is used to estimate values of a function between two known values. Pareto interpolation is an alternative to linear interpolation. In Pareto interpolation, the median is derived by interpolating between the logarithms of the upper and lower income limits of the median category. It is used by the Census Bureau in calculating median income within intervals wider than $2,500.

The data on marital status were derived from answers to long-form questionnaire Item 7, "What is this persons marital status," which was asked of a sample of the population. The marital status classification refers to the status at the time of enumeration. Data on marital status are tabulated only for the population 15 years old and over.
Each person was asked whether they were "Now married," "Widowed," "Divorced," "Separated," or "Never married." Couples who live together (for example, people in common-law marriages) were able to report the marital status they considered to be the most appropriate.

Never married includes all people who have never been married, including people whose only marriage(s) was annulled.
Ever married includes people married at the time of enumeration, along with those who are separated, widowed, or divorced.
Now married, except separated includes people whose current marriage has not ended through widowhood or divorce; or who are not currently separated. The category also may include people in common-law marriages if they consider this category the most appropriate. In certain tabulations, currently married people are further classified as "spouse present" or "spouse absent."
Separated includes people with legal separations, people living apart with intentions of obtaining a divorce, and people who are permanently or temporarily separated because of marital discord.
All people whose current marriage has not ended by widowhood or divorce. This category includes people defined above as "separated."
Married people whose wives or husbands were enumerated as members of the same household or the same group quarters facility, including those whose spouses may have been temporarily absent for such reasons as travel or hospitalization.
Married people whose wives or husbands were not enumerated as members of the same household or the same group quarters facility.
Married people whose wives or husbands were not enumerated as members of the same household, excluding separated. For example, this includes any person whose spouse was employed and living away from home, in an institution, or away in the armed forces.
Differences between the number of currently married males and the number of currently married females occur because of reporting differences and because some husbands and wives have their usual residence in different areas. These differences also can occur because different weights are applied to the individuals data. Any differences between the number of "now married, spouse present" males and females are due solely to sample weighting procedures. By definition, the numbers would be the same.

Census 2000 marital status definitions are the same as those used in 1990. A general marital status question has been asked in every census since 1880. While the marital status question in Census 2000 is identical to that of 1990, in Census 2000 the question was only asked on the long form, while in previous years it was asked on the short form.
