Nevertheless, some important associations emerge. For example, child poverty rates are higher when both the average household size and the adolescent fertility rate are higher, while the share of the population living in rural areas is negatively associated with relative child poverty. Having said that, only changes in the adolescent fertility rate share a negative association with within country trends in child poverty rates, which suggests that the decline in teenage pregnancies observed across the OECD in recent decades has contributed to reducing child poverty.
