EVER MARRIED WOMEN AND MEN
 
  Definition
 

Ever married women or men are persons who have been married at least once in their lives although their current marital status may not be “married”.

 
   
  Method of computation
 

The data are presented in terms of percentages of ever married persons by age group and sex. The numerator of each ratio is the sum of the number of persons who are currently married and those who are either divorced, widowed or separated.  The denominator is the total number of persons in the corresponding age group. The results are presented as percentages and are calculated separately for each sex. When data on consensual unions or visiting partnerships are reported, they are added to the numerator. The number of women or men with unknown marital status are excluded from both, the numerator and the denominator, implying that they are assumed to have the same distribution by marital status as the population that reported that status. Note that the percentage of never married women or men can be obtained by subtracting the percentage of ever married women or men from 100.

 
 

 

  Statistical system generating the data
 

Data on the population by age group, sex and marital status are generally obtained from censuses or sample surveys that include questions regarding the current marital status, age and sex of persons enumerated. Data derived from censuses are generally preferred because, when obtained through a questionnaire applied to the whole population, they are not affected by sampling variability.  However, reporting errors may nevertheless bias the results.

 
   
  Sources of the data presented
 

Data derived from censuses are generally reported by National Statistical Offices to the Statistics Division of the Department of Economic and Social Affairs of the United Nations Secretariat. Census data are also obtained from official census publications produced by National Statistical Offices. Adjusted data are only used when so reported by National Statistical Offices.

Survey programmes, such as the Demographic and Health Surveys (DHS) or the CDC-sponsored Reproductive Health Surveys (RHS), as well as national surveys are sources of the data required to calculate the percentages of ever married persons by age and sex.

In World Marriage Data 2008, estimates derived from a single source are presented for each reference year. In cases where more than one source could yield the required estimates, preference is given to estimates based on population censuses. In cases where the estimates can be derived from different surveys carried out the same year, preference is given to those derived from the larger survey.

For each data point included in the data files, information on the type of statistical system generating the data (census, survey) and on the exact source of the data (usually denoted by an acronym) is provided. The meaning of each acronym used is presented in the worksheet labeled "Sources". For surveys that are not part of an international survey programme, the full name is provided in the field "Survey name".

 
   
  Comments and limitations
 

The estimates by age may be affected by age misreporting. Marital status may be misreported, particularly in societies where divorce or separation is not socially acceptable. Data derived from surveys with small samples are subject to sampling error.

 
   
  Data coverage and reference years for the data reported
  World Marriage Data 2008 contains data on the percentage of ever married women and men for 217 countries or areas.  When available, data are presented for five reference dates: the closest years to 1970, 1985 and 1995, and the two most recent available years after 1999. Data for the five reference dates are available for 61 countries or areas.
