Wealth Gradient in HIV Infection: Women

Source: DHS for Burkina Faso (2003), Cameroon (2004), Ghana (2003), Kenya (2003), and Tanzania (2003).

Notes: The sample includes women ages 15–49 who were tested for HIV. The wealth index is the fraction of nine assets or amenities that the respondent’s household has; the assets and amenities are radio, television, refrigerator, bicycle, motorcycle, car, telephone, electricity, and a flush toilet or pit latrine (must have nonmissing values for at least five components to be included). Results are from Fan locally weighted regressions with a biweight quartic kernel with a halfwidth of 0.35, and are weighted using provided HIV sample weights.
