Comparability — General

The universe differs considerably across samples. Some samples restrict the universe to women who have given birth, while others restrict only by age. Most limit the universe to females of child-bearing age, but some limit only the lower end of the age range. A few samples restrict the universe to ever-married females.

The variable is top-coded at 4 or more births.

In many samples, the variable indicates only whether or not a woman had a child, not the number: Argentina 2001, Brazil 2010, Indonesia 2010, Liberia 2008, Panama 1990-2010, Nepal 2001, St Lucia 1980-1991, Sierra Leone 2004, and U.S. 2005-2010.

Comparability — Argentina [top]

The 1980 and 1991 data are top-coded at 2 or more children. The 2001 sample only indicates whether a woman had a child, not the number of children.

Comparability — Botswana [top]

In the 1991 and 2001 samples, BIRTHSLYR is calculated from separate variables for male and female children. The 2011 data are top-coded at 2 or more children.

Comparability — Burkina Faso [top]

In all sample years, data are calculated from separate variables for male and female children.

Comparability — Cambodia [top]

The data are calculated from separate variables for male and female children and are top-coded at two or more births in all years. Sex-specific data are retained in the source variables.

Comparability — Cameroon [top]

The universe changes significantly over time. The 1976 question was asked of women between 15 and 45 years old. In 1987 and 2005, the question was asked of women age 12 and older.

In 1976 and 1987, data are calculated from separate variables for male and female children.

Comparability — China [top]

In 2000, the data report only whether there was a birth, not the number.

Comparability — Ethiopia [top]

Only long-form female respondents (20%) were asked the question in 2007.

Comparability — Ghana [top]

The universe changes over time. In the 2000 sample, the question was asked of women age 12-49, while in 2010, it was asked of women age 12-54.

Comparability — Guinea [top]

The data were calculated from separate census questions for male and female children and are top-coded at 3 or more children.

Comparability — Iran [top]

Only ever-married women were asked census questions on fertility history. In the 2011 sample, BIRTHSLYR is calculated from separate variables for male and female children. The data are top-coded at 2+ for all samples.

Comparability — Jamaica [top]

The universe differs between samples. In the 1982 sample, the question is asked of women age 14 and older who are not attending school fulltime and not in selected group quarters. In the 1991 sample, the universe is restricted to women between 14 and 64 years old who are not attending school fulltime and not in selected group quarters. In the 2001, the question is asked of women between 14 and 49 years old.

The 1982 sample is top-coded at 3+ children within the year, whereas other samples are top-coded at 2+ children. The 1982 data indicate more women with 3+ children born than two children, which is cause for some skepticism with this variable.

Comparability — Laos [top]

The variable is constructed from separate variables for male and female births in the last one year. The data are top-coded at two or more births. Sex-specific data are available in the source variables.

Comparability — Liberia [top]

There are differences between the samples both in terms of universe and coding. In 1974, the universe was females age 10+, while in 2008, it was females age 12-54. Additionally, the 1974 sample indicates the number of children born in the past year (top-coded at 2), while the 2008 sample only provides information on whether there was a birth in the last year or not.

Comparability — Malawi [top]

The universe differs marginally between samples. In the 1987 sample, the question is asked of women age 10 and older. In the 1998 sample, the question is asked of women age 12 and older.

The data for 1987 and 1998 are calculated from separate variables for male and female children.

Comparability — Mozambique [top]

The universe varies significantly across samples: the 1997 census addressed the question only to women age 12 to 50, while the 2007 sample includes all female residents age 12 and older.

For both samples the data are constructed from separate variables for boys and girls.

Comparability — Nepal [top]

The universe is restricted to ever-married women.

The variable is constructed from separate variables for male and female births in the last one year. The data are top-coded at four or more births. Sex-specific data are available in the source variables.

Comparability — Nicaragua [top]

The data apply to births in calendar year 1970.

Comparability — Palestine [top]

The age universe differs substantially between samples. Only ever-married women were asked the census question in both samples. In the 1997 sample, the question is asked of ever-married women age 12 and older. In the 2007 sample, the question is asked of ever-married women between 12 and 59 years of age.

Comparability — Panama [top]

The 1980 sample reports the number of children in the last 12 months, the 1990 and 2000 samples indicate only whether any child was born.

The age universe differs significantly among samples: from 15 to 50 in 1970, to 15 and older in 1990, to 12 to 49 in 2000-2010.

Comparability — Philippines [top]

The 2010 sample is top-coded at 2+ births.

Comparability — Rwanda [top]

The 2002 and 2012 data are top-coded at 3 or more children. For all samples the data were calculated from multiple census questions for male and female children.

Comparability — Saint Lucia [top]

The samples have different age universes and both samples restrict the question to women who were not in school. In the 1980 sample, the question is asked of women age 14 and older who are not attending school fulltime. In the 1991 sample, the question is asked of women between 15 and 65 years old who are not attending school.

Comparability — Senegal [top]

The 1988 sample is top coded at 3 or more children born last year, while the 2002 sample is top coded at 4 or more. The data for both samples were calculated from separate census questions for male and female children.

Comparability — South Africa [top]

The data report only whether there was a birth, not the number.

Comparability — South Sudan [top]

The data are calculated from two separate variables and top-coded at 2 or more children.

Comparability — Tanzania [top]

The 2002 sample is top-coded at 2 or more births last year. For 1988 and 2002, BIRTHSLYR is calculated from separate census questions for male and female children.

Comparability — Togo [top]

The data are top-coded at two or more births last year.

Comparability — Trinidad and Tobago [top]

The 2000 and 2011 samples are top-coded at 2 or more births last year.

Comparability — Uruguay [top]

The 1975, 1985, and 1996 samples have a variable that explicitly lists the number of children born in the previous year. The 1985 sample is top-coded at 3 children, while the other two samples are top-coded at 2 children.

In 1975 and 1996, the universe is women age 15 or older. For the 1985 sample, the universe is females age 15+ who had children born alive.

Comparability — Venezuela [top]

The universe changes over time. In the 1981 sample, the question is asked of women age 12 and older who ever gave birth. In the 1990 sample, the question is asked of women between 12 and 59 years old who ever gave birth.

Comparability — Zambia [top]

The universe varies slightly across samples.

The variable is calculated from several input variables. In the 2000 sample, a small number of cases (less than 25) were top-coded at 1 for two of the input variables for confidentiality reasons. In these cases, the values in BIRTHSLYR will be incorrect.
