The pandemic crisis wrecked an unprecedented havoc to the world. There is dire need for understanding population dynamics as societies around the world strive to achieve the ambitious and holistic 2030 Sustainable Development Goals (SDGs). An educated, skilled healthy and empowered population is the key driver of development; person which is ignorant and uneducated and enfeebled by disease and unemployment is a drag on development and a recipe for persistent and growing poverty. It is pertinent to mention that the developing countries have been devastated in the last 2 years by the coronavirus pandemic and natural and man-made disasters, as well as price inflation in food, energy and other essential commodities, requiring mobilization of adequate finance to respond to these multiple exogenous shocks to their economies and people. Apart from such emergency measures, the realization of the demographic dividend for the developing countries, and realization of the SDGs, requires comprehensive national and international policy actions including: a priority focus on human development, with adequate spending on quality education and health, especially the empowerment of women and youth in development; adequate investment in sustainable infrastructure – energy, transportation, agriculture, housing, which can create jobs, ensure economic growth and lay the foundation for industrialization and sustained growth; the construction of an equitable international financial architecture, including a fair international tax system reform of the world trade regime to allow developing countries preferential and full access to global markets for goods and services to enable export-led growth overcoming the growing digital divide between the industrial and developing countries, and, halting and reversing the outflow of billions each year in illicit financial flows from developing countries.
