Condoms are most effective when their use is consistent, rather than occasional. The current indicator
will provide an overestimate of the level of consistent condom use. However, the alternative method of
asking whether condoms are always/sometimes/never used in sexual encounters with clients in a specified period is subject to recall bias. Furthermore, the trend in condom use in the most recent sexual act will generally reflect the trend in consistent condom use.

This indicator asks about commercial sex in the past twelve months. If you have data available on another time period, such as the last 3 or 6 months, please include this additional data in the comments section of the reporting tool.
 Surveying sex workers can be challenging. Consequently, data obtained may not be based on a representative sample of the national, most-at-risk population being surveyed. If there are concerns that the data are not based on a representative sample, these concerns should be refl ected in the interpretation of the survey data. Where different sources of data exist, the best available estimate should be used. Information on the sample size, the quality and reliability of the data, and any related issues should be included in the report submitted with this indicator.

To maximize the utility of these data, it is recommended that the same sample used for the calculation of
this indicator be used for the calculation of the other indicators related to these populations.
