Wealth Gradient in HIV Infection: Men

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

Notes: The sample includes men ages 15–59 (Burkina Faso, Cameroon, and Ghana), 15–54 (Kenya), and 15–49 (Tanzania) 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.
