Figure 2

Secular trend of relative difference in mean birth weight among neonates born to mothers with high and low educational attainment, 1996–2013. The Fig. 2 shows the secular trend of relative difference in mean birth weight among neonates born to mothers with high and low educational attainment in Brazilian capitals from 1996 to 2013. This figure shows a single curve constructed from the difference between the mean birth weight of newborn children of mothers with higher education and the mean birth weight of newborn children of mothers with less education, year by year. This relative difference in mean birth weight between the two extremes of maternal education showed a downward trend over the study period.
