The 20th anniversary edition of UNDP’s annual Human Development Report documents extraordinary and often overlooked progress in health and education in most developing countries over the past four decades, as measured by the Report’s Human Development Index. Though these advances have not been consistent or universal, children in most countries today can look forward to much longer, healthier and more productive lives than those enjoyed by their grandparents. To illustrate this profound transformation, UNDP asked four multi-generation families — Brazilians, Congolese, Indonesians and Kenyans– to tell in their in their own words of how lives and their countries have changed over the years.
