FIGURE 2.

Relationship between health spending and antenatal HIV prevalence (a), infant mortality rates (b), income per capita (c), and White population (d): South Africa's provinces, 1996–2007.

Note. Bars above the x-axis indicate a positive correlation; bars below indicate a negative correlation. Pearson coefficients are presented for 46 correlations across South Africa's 9 provinces for each year from 1996 to 2007. Higher public spending was associated with higher levels of antenatal HIV prevalence, income per capita, White population, and infant mortality (r > 0). Infant mortality and income per capita are used in log form to adjust for positive skew. Similar results were observed using Spearman correlations and relative health spending data (data not shown).

Source. Data on income per capita and White population ranking were obtained from the Statistics South Africa database. Data on antenatal HIV prevalence and infant mortality rates were obtained from the South Africa Health Systems Trust database and were available for 1996–2007 and 1998–2007, respectively.
