And the UN predicts an average life expectancy of 77.2 years by 2050. </p><p>The result, combined with the decline in fertility, is that the proportion of people over 65 is expected to rise from 10 percent in 2022 to 16 percent in 2050.</p><p>This global graying will have an impact on labor markets and national pension systems, while requiring much more elderly care.</p><p>Snow says that a growing number of countries are reaching out to her organization, asking &quot;how can UNFPA help us better understand what we might do to boost our population.&quot;</p><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=2304735" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div><div><strong>Unprecedented diversity </strong></div><p>Beneath the global averages are some major regional disparities.</p><p>For example, the UN projects that more than half of the population growth by 2050 will come from just eight countries: Democratic Republic of Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.</p><p>The average age in different regions is also meaningful, currently at 41.7 years in Europe versus 17.6 years in Sub-Saharan Africa, according to Snow, who says the gap &quot;has never been as large as it is today.&quot;</p><p>Those numbers could even out, but unlike in the past when countries&#x27; average ages were mostly young, says Snow, &quot;in the future, we may be closer in age, mostly old.&quot;</p><p>Some experts believe these regional demographic differences may play a significant role in geopolitics going forward.</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/07/06/22/popcom-eyes-1-pct-yearly-population-growth">Popcom wants to keep yearly population growth at around 1 million</a></li></ul><div><strong>India to surpass China</strong></div><p>In another illustration of changing trends, the two most populous countries, China and India, will trade places on the podium as early as 2023, according to the UN.</p><p>China&#x27;s 1.4 billion population will eventually begin to decline, falling to 1.3 billion by 2050, the UN projects.</p><p>By the end of the century, the Chinese population could fall to only 800 million.</p><p>India&#x27;s population, currently just below that of China, is expected to surpass its northern neighbor in 2023, and grow to 1.7 billion by 2050 -- though its fertility rate has already fallen below replacement level.</p><p>The United States will remain the third most populous country in 2050, the UN projects, but it will be tied with Nigeria at 375 million.</p><p>abd-des/tjj/bfm/dw/smw</p><p>© Agence France-Presse</p><figure class="op-interactive"><iframe height="315" src="https://www.youtube.com/embed/DbFwGBddXZM?enablejsapi=1" width="560"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div>
