Demography [New] The historic rate of rising life expectancy implies a global average of 92 years by 2100: But the United Nations' medium fertility scenario rather conservatively projects that average global life expectancy at the end of the century will instead be 83. US life expectancy at birth is projected to be 82.4 years in 2048, 0.4 years shorter than CBO pro- jected last year, and life expectancy at age 65 is projected to be 21.5 years, 0.2 years shorter than in last year's projection. CBO now projects approximately 970,000 (or 0.9 percent) more US deaths over the next three decades than the agency projected last year. Between 2019 and 2029, projected US net inflows account for approximately half of overall population growth, but by the last decade of the projection period that share is about four-fifths of all growth. CBO projects that total US fertility rates will remain below the replacement rate - the fertility rate required for a generation to exactly replace itself - of 2.1 children per woman for the next three decades. With birth rates projected to remain low, net immigration flows become an increasingly important part of overall U.S. population growth; in 2019, pro- jected net inflows account for approximately 45 percent of overall population growth, but by 2049 that share is nearly 87 percent. Immigration will prop up population growth in North America - The UN data suggests that the United States will experience a population increase of 85 million leading up to 2100 thanks to immigration, which will keep the population growing steadily. If the current rate of road deaths does not change - that is, the rate of 4.58 deaths per 100,000 remains constant, while the population grows - it is estimated that over the next five years, around 6,000 lives will be lost on Australia's roads. More than 80 countries worldwide already have fertility rates lower than replacement levels, and by 2050, the share of the global population above 65 is expected to rise to 16%, up from 8% today and 5% in 1950. The world is already facing a low fertility rate that is expected to fall further to the point where no country is expected to have a fertility rate of more than five births per woman by 2050. Malaysia has reach proportion of 77 percent of population living in cities and expected to raise to 80 percent by year 2030. Due largely to immigration, the United States is expected to gain 100 million people by 2100 while the populations of China, Germany, Japan, Russia and much of Europe are expected to drop precipitously. The number of Muslims living in Austria has grown consistently since the 1970s from 22, 2067 in 1971 to 158,776 in 1991 to 515,914 in 2002 and 700,000 in 2016, and even without further immigration, Austria's Muslim population is expected to grow significantly in the future. Two-thirds of the projected growth of the global population through 2050 will be driven by current age structures and would occur even if childbearing in high-fertility countries today were to fall immediately to around two births per woman over a lifetime. Migration is the driver of all of Scotland's recent population growth, and it is projected that 100% of population growth in the future will be from immigration, from both overseas and the rest of the UK. Most models used for analysing population trends suggest that, in the coming years, the EU's population will continue to age as a result of consistently low levels of fertility and extended longevity. Over the next century Africa will replace Asia as the driver of global population increase and the impact of climate change will be severe. Today, on average, women in Sub-Saharan Africa have 4.8 children per woman, compared with less than 3 children per woman worldwide, and the fertility in Sub-Saharan Africa is projected to remain substantially higher than in any other region for the next few decades. The 'middle-of-the-road' scenario expects a global population of 9.2 billion people with a medium per-capita GDP, whereas the most pessimistic scenario has a population approaching 10 billion people with a low per-capita GDP. An increase in the rate of urbanisation could result in 69.9% of the population living in urban areas by 2050, up from 45.2% in 2012. The WHO's End TB Strategy target of reducing TB mortality by 90% by 2030 will not be reachable without a substantial increase in global TB R&D investment, from $772 million per year in 2017 to at least $2 billion per year during the next four years. Most countries classified today among developing countries are expected to experience a demographic transition from a combination of high natality and high mortality to a post-transition state of low natality with low mortality.
