Comparing international and national data on MDG Indicator 5.4
adolescent birth rate
Kyrgyzstan
International definition
The adolescent birth rate measures the annual number of births to women 15 to 19 years of age per 1,000 women in that age group. It represents the
risk of childbearing among adolescent women 15 to 19 years of age.
Calculation of estimates for MDG monitoring
The adolescent birth rate is generally computed as a ratio, which is then multiplied by 1,000. The numerator is the number of live births to women 15
to 19 years of age, and the denominator an estimate of exposure to childbearing by women 15 to 19 years of age.
In the case of civil registration the numerator is the registered number of live-births born to women 15 to 19 years of age during a given year, and the
denominator is the estimated or enumerated population of women aged 15 to 19.
In the case of survey data, the numerator typically refers to births to women that were 15 to 19 years of age at the time of the birth during a reference
period before the interview, and the denominator to person-years lived between the ages of 15 and 19 by the interviewed women during the same
reference period.
In the case of census data, the adolescent birth rate is generally computed based on the date of last birth or the number of births in the 12 months
preceding the enumeration.
Process used by international agencies for obtaining data from national sources
Civil registration data are obtained from country-reported data compiled by the United Nations Statistics Division or regional Statistics Divisions or
statistical units. Additional data is also obtained from nationally sponsored surveys, and directly from census reports. Population figures are obtained
from the UN Population Division.
National data sources
Data is obtained from civil registration systems; surveys such as the Demographic Health Surveys, the CDC-assisted Reproductive Health Surveys,
MICS and other nationally sponsored surveys; and censuses.

3)
The use of different denominators when calculating the ratio
The inclusion of births to women under 15 years of age
For survey data, there may be discrepancies on the dating and the actual figure if a different reference period is being used

UNPD explained that the data are obtained
from UNSD; if no data available at UNSD then
UNPD may contact another office.
Treatment of births with age of mother
unknown:
UNPD distributes them in
proportion to the size of each age
group
NSO will investigate what’s the
national procedure on this
FOLLOW-UP:
- Investigate cause of big data differences (is
the NSo considering mothers of age below
15?)
