Condom use at last high-risk sex is the percentage of young men and women aged 15–24 reporting the use of a condom during sexual intercourse with a non-cohabiting, non-marital sexual partner in the last 12 months.
The indicator is calculated by dividing the number of respondents ages 15–24 reporting using a condom during sexual intercourse with a non-marital and non-cohabiting sexual partner in the last 12 months, divided by the number of respondents ages 15–24 reporting having had sex with a non-cohabitating, non-marital sexual partner in the last 12 months.
The data from household surveys used to produce this indicator are weighted according to the survey design to create a nationally representative indicator. No additional alterations are made to the data.
A rise in the indicator is a sign that condom promotion campaigns are having the desired effect among their main target market. However, condom promotion campaigns aim for consistent use of condoms with non-regular partners rather than simply occasional use. Some surveys have tried to ask directly about consistent use, but the question is subject to recall bias and other biases. The current indicator is therefore considered adequate to address the target since it is assumed that if consistent use rises, use at last high-risk sex will also increase.
In principle, there is no discrepancy between global and national figures, as national data are not modified.
These data are collected through household surveys, such as Multiple Indicator Cluster Surveys (MICS) and Demographic and Health Surveys (DHS), reproductive and health surveys and behavioural surveillance surveys. The results are reported regularly in the final reports of these surveys. In addition, most data are available at
Nationally representative population-based surveys, such as DHS and MICS, are conducted by national statistical offices or other relevant government offices under the supervision of government or international agencies.
As part of routine data quality control, survey results are checked for inconsistencies and to ensure that data are collected using a clearly defined population-based sampling frame, permitting inferences to be drawn for the entire population. UNICEF also conducts an annual exercise called the Country Reports on Indicators for the Goals (CRING), in which data maintained in the global databases at UNICEF for indicators regularly reported by UNICEF, are sent to countries for validation and updating. Updates from countries must be accompanied by original source documentation, e.g. survey reports.
No adjustments are made to the data compiled from DHS, MICS and other surveys that are statistically sound and nationally representative.
There is no treatment of missing values. When the information needed to calculate the indicator is not available, the indicator is not estimated.
Data are available from approximately 30 countries.
The lag between the reference year and actual production of data series depends on the availability and reliability of the survey for each country. Household surveys, such as Demographic and Health Surveys, reproductive and health surveys and Behavioural Surveillance Surveys, are generally conducted every three to five years.
Household surveys, such as DHS and MICS, are in general implemented every 3-5 years with results published within a year of field data collection. Data from national-level household surveys are compiled in the UNICEF global databases and are published annually by UNICEF in The State of the World’s Children report, and are available at http://www.childinfo.org
Regional and global estimates are based on population-weighted averages weighted by the total number of young women and men 15-24 years of age. These estimates are presented only if available data cover at least 50% of total men and women 15-24 years of age in the regional or global groupings.
Available data are published in annual reports, at the end of the calendar year, by UNICEF in The State of the World’s Children, Children and AIDS Stock Taking Report and are available at http://www.childinfo.org.
