This indicator shows the prevalence of HIV that is measured in a national survey of women attending public-sector antenatal clinics for the first time in their current pregnancy. The data are derived from the Department of Health's antenatal HIV prevalence surveys. Weighted population numbers are not available for all years, and the standard disaggregations for children do not apply to this indicator.

Notes | Sample surveys are always subject to error, and the proportions simply reflect the mid-point of a possible range. The confidence intervals (CIs) indicate the reliability of the estimate at the 95% level. This means that, if independent samples were repeatedly taken from the same population, we would expect the proportion to lie between upper and lower bounds of the CI 95% of the time. The wider the CI, the more uncertain the proportion. Where CIs overlap for different sub-populations or time periods we cannot be sure that there is a real difference in the proportion, even if the mid-point proportions differ. CIs are represented in the bar graphs by vertical lines at the top of each bar. |
