Increases are expected to be largest in countries where life expectancy is lower , contributing to a convergence of increased life expectancy across geographies . The trend is largely driven by public health measures that have prevented and improved survival rates from cardiovascular diseases , COVID-19, and a range of communicable , maternal , neonatal , and
