| xiv | By July 2005, the world will have 6.5 billion inhabitants, 380 million more than in 2000 or a gain of 76 million annually. Despite the declining fertility levels projected over 2005-2050 the world population is expected to reach 9.1 billion according to the medium variant and will still be adding 34 million persons annually by mid-century. | world population growth predictions |
| xiv | Today, 95 per cent of all population growth is absorbed by the developing world and 5 per cent by the developed world. By 2050, according to the medium variant, the population of the more developed countries as a whole would be declining slowly by about 1 million persons a year and that of the developing world would be adding 35 million annually, 22 million of whom would be absorbed by the least developed countries. | world population growth predictions |
| xiv | A fertility path half a child below the medium [variant prediction] would lead to a population of 7.6 billion by mid-century. That is, at the world level, continued population growth until 2050 is inevitable even if the decline of fertility accelerates. | world population growth predictions |
| xv | Because of its low and declining rate of growth, the population of developed countries as a whole is expected to remain virtually unchanged between 2005 and 2050, at about 1.2 billion. In contrast, the population of the 50 least developed countries is projected to more than double, passing from 0.8 billion in 2005 to 1.7 billion in 2050. Growth in the rest of the developing world is also projected to be robust, though less rapid, with its population rising from 4.5 billion to 6.1 billion between 2005 and 2050. | world population growth predictions poverty development wealth |
| xv | The population of 51 countries or areas, including Germany, Italy, Japan, the Baltic States and most of the successor states of the former Soviet Union, is expected to be lower in 2050 than in 2005. | population decline development |
| xv | During 2005-2050, nine countries are expected to account for half of the world?s projected population increase: India, Pakistan, Nigeria, the Democratic Republic of Congo, Bangladesh, Uganda, the United States of America, Ethiopia and China, listed according to the size of their contribution to population growth during that period. | world population growth development |
| xvii | In 2000-2005, fertility at the world level stood at 2.65 children per woman, about half the level it had in 1950-1955 (5 children per women). In the medium variant, global fertility is projected to decline further to 2.05 children per woman by 2045-2050... In developed countries as a whole fertility is currently 1.56 children per woman and is projected to increase slowly to 1.84 children per woman in 2045-2050. In the least developed countries, fertility is 5 children per woman and is expected to drop by about half, to 2.57 children per woman by 2045-2050. In the rest of the developing world, fertility is already moderately low at 2.58 children per woman and is expected to decline further to 1.92 children per woman by mid-century, thus nearly converging to the fertility levels by then typical of the developed world. Realization of the fertility declines projected is contingent on access to family planning, especially in the least developed countries. | world population growth development fertility |
| xvii | In 2000-2005, fertility remains above 5 children per woman in 35 of the 148 developing countries, 30 of which are least developed countries... Overall, the countries with high fertility account for 10 per cent of the world population. In contrast, fertility has reached below-replacement levels in 23 developing countries accounting for 25 per cent of the world population. This group includes China whose fertility during 2000-2005 is estimated at 1.7 children per woman. | world population growth development fertility |
| xvii | Fertility levels in the 44 developed countries, which account for 19 per cent of the world population, are currently very low. All except Albania have fertility below replacement level and 15, mostly located in Southern and Eastern Europe, have reached levels of fertility unprecedented in human history (below 1.3 children per woman). Since 1990-1995, fertility decline has been the rule among most developed countries. The few increases recorded, such as those in Belgium, France, Germany, the Netherlands and the United States, have been small. |

| xix | In developed countries, 20 per cent of today?s population is aged 60 years or over and by 2050 that proportion is projected to be 32 per cent. The elderly population in developed countries has already surpassed the number of children (persons aged 0-14) and by 2050 there will be 2 elderly persons for every child. In the developing world, the proportion of the population aged 60 or over is expected to rise from 8 per cent in 2005 to close to 20 per cent by 2050. | population growth development aging |
| xix | During 2005-2050, the net number of international migrants to more developed regions is projected to be 98 million or an average of 2.2 million annually. The same number will leave the less developed regions. For the developed world, such a level of net migration will largely offset the expected excess of deaths over births during 2005-2050, which amounts to a loss of 73 million people. For the developing world, the 98 million emigrants represent scarcely less than 4 per cent of expected population growth. | population growth immigration emigration |
