Median Income of Families by Type of Family in Current and Constant (2005) Dollars: 1947 to 2005

Added By Infochimps

The Statistical Abstract files are distributed by the US Census Department as Microsoft Excel files. These files have data mixed with notes and references, multiple tables per sheet, and, worst of all, the table headers are not easily matched to their rows and columns.

A few files had extraneous characters in the title. These were corrected to be consistent. A few files have a sheet of crufty gibberish in the first slot. The sheet order was shuffled but no data were changed.

The tables that were changed (this is table 677):

0166 0257 0362 0429 0445 0446 0459 0461 0462 0464 0465 0466 0467

This dataset consists of a table of 127 rows and 19 columns.

  2. Data reflect implementation of expanded income questions to show wage and salary, farm self-
    employment, nonfarm self-employment, and all other nonearned income separately.
  3. Data reflect implementation of 1950 census population controls.
  4. Data reflect implementation of first hotdeck procedure to impute missing income entries (all income
    data imputed if any missing). Data also reflect introduction of 1960 census-based sample design.
  5. Data reflect full implementation of 1960 census-based sample design and population controls.
  6. Data reflect implementation of new procedures to impute missing data only.

  11. Data reflect implementation of a new March CPS processing system. Questionnaire expanded to ask
    eleven income questions.
  12. Some of these estimates were derived using Pareto interpolation and may differ from published data
    which were derived using linear interpolation.
  13. First year medians were derived using both Pareto and linear interpolation. Before this year, all medians

    CURRENT POPULATION SURVEY (MARCH ANNUAL DEMOGRAPHIC SURVEY)
    Approximately 62,500 housing units were eligible to receive the 1995 Annual Demographic Survey. The basic monthly CPS
    sample of 60,000 housing units was supplemented by 2,500 housing units which had at least one Hispanic member the
    previous November. In addition, members of the Armed Forces, which are excluded from the basic CPS labor force survey,
    were part of the elibigle population in March. Because of the CPS sample rotation system, approximately one-half of the
    sample had been interviewed the previous March.
    Interviewers used lap-top computers to administer the interview, asking questions as they appear on the screen and directly
    entering the responses obtained. With the exception of first and the fifth month-in-sample interviews, when an interviewer
    usually visited the sample unit, over 90 percent of the interviews were conducted by telephone.
    Completed interviews were electronically transmitted to a central processor where the responses were edited for consistency,
    imputations were made for missing data, and various codes were added. Based on the probability of selection, a weight was
    added to each supplement-responding household and person record so that estimates of the population by state, race, age,
    sex, and Hispanic origin matched the population projections made by the Bureau of the Census. Since not every person who
    provided labor force information completed the supplement and the supplement was asked of members of the Armed Forces,
    the supplement weights vary from those used for labor force estimation.
    DEFINITIONS
    Family
    The term “family” refers to a group of two or more persons
    related by birth, marriage, or adoption who reside together;
    all such persons are considered as members of one family.
    For example, if the son of the person who maintains the
    household and the son’s wife are members of the household, they
    are treated as members of the parent’s family. Every family must
    include a reference person (see definition of householder for
    primary families); two or more people living in the same
    household who are related to one another, but are not related to
    the householder, form an “unrelated subfamily.” Beginning with
    the 1980 CPS, unrelated subfamilies were excluded from the count
    of families and unrelated subfamily members were excluded from
    the count of family members.
    Family households
    Family households are households maintained by a family (as
    defined above). Members of family households include any
    unrelated persons (unrelated subfamily members and/or secondary
    individuals) who may be residing there. The number of family
    households will not equal the number of families since families
    living in group quarters are included in the count of families.
    In addition, the count of family household members differs from
    the count of family members in that the family household members
    include all persons living in the household, whereas family
    members include only the householder and his/her relatives.
    (See the definition of family).
    Income
    For each person in the Current Population Survey (CPS) sample
    15 years old and over, questions were asked on the amount of
    money income received in the preceding calendar year from each
    of the following sources: 1) earnings from longest job (or self-
    employment); 2) earnings from jobs other than longest job; 3)
    unemployment compensation; 4) worker’s compensation; 5) Social
    Security; 6) Supplemental Security income; 7) public assistance;
    8) veterans’ payments; 9) survivor benefits; 10) disability
    benefits; 11) pension or retirement income; 12) interest; 13)
    dividends; 14) rents, royalties, and estates and trusts; 15)
    educational assistance; 16) alimony; 17) child support; 18)
    financial assistance from outside of the household, and other
    periodic income. Capital gains and lump-sum or one-time payments
    are excluded. For definitions of alternative measures of income
    (definitions 1 through 15 shown in tables 10 through 12), see
    introductory text.
    It should be noted that although the income statistics refer to
    receipts during the preceding calendar year, the demographic
    characteristics such as age, labor force status, and family or
    household composition are as of the survey date. The income of
    the family/household does not include amounts received by persons
    who were members during all or part of the income year if these
    persons no longer resided in the family/household at the time of
    interview. However, income data are collected for persons who
    are current residents but did not reside in the household during
    the income year.
    Data on consumer income collected in the CPS by the Bureau of the
    Census cover money income received (exclusive of certain money
    receipts such as capital gains) before payments for personal
    income taxes, Social Security, union dues, Medicare deductions,
    etc. Therefore, money income does not reflect the fact that some
    families receive part of their income in the form of noncash
    benefits such as food stamps, health benefits, noncash benefits
    in the form of rent-free housing and goods produced and consumed
    on the farm; or that non-cash benefits are also received by some
    nonfarm residents which often take the form of the use of
    business transportation and facilities, full or partial payments
    by business for retirement programs, medical and educational
    expenses, etc. These elements should be considered when
    comparing income levels. Moreover, readers should be aware that
    for many different reasons there is a tendency in household
    surveys for respondents to underreport their income. From an
    analysis of independently derived income estimates, it has been
    determined that income earned from wages or salaries is much
    better reported than other sources of income, and is nearly equal
    to independent estimates of aggregate income.
    Median income
    Median income is the amount which divides the income distribution
    into two equal groups, half having incomes above the median,
    half having incomes below the median. The medians for households,
    families, and unrelated individuals are based on all households,
    families, and unrelated individuals. The medians for persons are
    based on persons 15 years old and over with income.
    Mean income
    Mean income is the amount obtained by dividing the total
    aggregate income of a group by the number of units in that
    group. The means for households, families, and unrelated
    individuals are based on all households, families, and unrelated
    individuals. The means for persons are based on persons 15 years
    old and over with income.
