These higher growth rates meant that Piketty’s inequality, r > g, was reversed contributing to a reduction of the concentration of capital and declining levels of inequality. If population growth and per capita GDP growth are completely independent, higher population growth rates would clearly lead to higher economic growth rates. On the other hand, for an underdeveloped country with high population density and a high percentage of employable people, any increase in population will be detrimental to its economy. Because population growth plays an important role in overall economic growth, the evolution of world population will continue to be a major global concern. Population growth is falling in many parts of the world and once the demographic transition is completed in sub-Saharan Africa and other areas of robust population growth, world population growth will probably return to historic levels of less than 1% per year. Meeting this increased demand without causing irreversible damage to the environment may be challenging but the rapid adoption of more sustainable agricultural practices currently under way suggests that this is not an insurmountable task. In low-income countries, rapid population growth is likely to be detrimental in the short and medium term because it leads to large numbers of dependent children. First, if Piketty’s analysis is correct, slow economic growth may continue to be a factor in rising inequalities in the distribution of income and wealth. To measure MFP, it is necessary to determine the value of total output (GDP) and the contribution of the combined inputs, capital and labor, with MFP calculated as the amount of output that can be obtained from a unit of the combined inputs (OECD, 2016, pp. Higher population growth is generally associated with larger families and large families will have to divide inheritances among more children. Setting A at 3.04 billion, V at 7.35 billion, and t at 55 and solving the formula for r gives an estimate of average annual compound population growth over this period of 1.61%. Does this mean that countries with higher population growth rates will benefit from greater overall economic growth potentially mitigating the effects on inequality that concern Piketty? In fact, per capita GDP growth in the EU outpaced that of the United States where economic growth would have averaged 2.41% instead of 3.04% if the U.S. population had increased at the same rate as that of the EU. Such an outcome is consistent with arguments advanced by Simon (1990) who suggested that greater population growth would result in a larger “stock of useful knowledge” (p. 168) which would, in turn, foster greater per capita economic growth. The implicit assumption in these analyses is that future technological innovations will be unable to overcome resource scarcities created by the needs of the growing population without causing environmental damage. In Japan, where population growth is negative, 13% of the population is under age 15 with 26% over 65 (World Bank, 2017). . Health performance and economic performance are interlinked. In other words, rising prices for petroleum and other natural resources are likely to stimulate innovations that will solve many of the problems generated by the increasing scarcity that will lead to the rising prices. Connor (2016) suggests that economic growth in these countries and the availability of short-term work visas have attracted large numbers of migrants with the number of foreign-born residents growing by 61% between 2005 and 2015. In a later article, Piketty (2015) clarifies this result noting that other factors as well as economic policies contribute importantly to the evolution of economic inequality, suggesting that large gaps between r and g will tend to amplify the effects of these other factors. Average Annual Growth Rates of Population, Per Capita GDP, and GDP, World Regions, 1820 to 1913, 1913 to 2010, and 1820-2010. Note, however, that the reason for this difference is not that the United States had greater growth in per capita output but rather that U.S. population growth was higher. Population, health, and the environment  (PHE) is an approach to human development that integrates family planning and health with conservation efforts to seek synergistic successes for greater conservation and human welfare outcomes than single sector approaches.There is a deep relationship between population, health and environment. Average annual world population growth over this period was about 1% but has varied considerably across regions and over time. [Some fundamental problems concerning the relationship between population growth and economic development]. Net Migration (2012) and Foreign-Born Population (Total and Percent, 2015), World Regions and Selected Countries. How did we get here? As population growth rates have begun to fall in recent years, the possibility that food and natural resources will be exhausted by a larger population seems to be less of a preoccupation than the more likely danger that continued use of the earth’s resources at current rates will lead to climate change and other environmental problems. As a result, the natural population growth rate is likely to be very low. The free movement of workers within countries has long been one of the strengths of market economies. In 2012, about 15 million people emigrated from low- and moderate-income countries while high-income countries received about an equal number. Economic growth is measured by changes in a country’s Gross Domestic Product (GDP) which can be decomposed into its population and economic elements by writing it as population times per capita GDP. the relationship between population growth and economic development. For the decade of the 1990s, annual growth in per capita output in these countries averaged 1.37% compared with a rate of 4.15% for the period 2000-2015 (Table 5). A different type of dependency problem exists in many African countries where relatively small working-age populations are required to support the very large number of children who have important educational and health needs. While European population growth rates slowed during the period 1913 to 2010, they accelerated somewhat in Africa, Asia, and Latin America. Similarly, to the extent that increased incomes will increase the range of choices and capabilities enjoyed by households and governments, economic growth will enhance human development. Huang and Xie (2013) find that current population growth has a negative effect on economic growth while lagged population growth has a positive effect so that there is no long-term relationship between these variables. Average annual growth in per capita output has also been fairly modest over the past 200 years accelerating during periods when very poor countries begin to catch up with more highly developed economies or when rapid productivity growth is achieved as was the case in many countries during the 20th century. Fig. Average Annual Percentage Growth of Population, Real Per Capita GDP, and Real GDP (2010 US$), World Regions and Selected Countries, 1990 to 2000 and 2000 to 2015. When substantial deposits of petroleum became accessible in North Dakota (USA), economic activity picked up greatly attracting large numbers of workers from less prosperous parts of the United States and easing the labor shortages that had arisen with the onset of the oil boom (Healy, 2016). If popula-tion growth was too rapid, wages would be depressed, causing famine or … I. The World Bank (2017) publishes an online database with a great many socioeconomic variables, including population and real GDP, from 1960 to the present for most countries and world regions. In contrast, deaths in Japan outnumbered births and with virtually no net migration, the country had a negative population growth rate of −0.2% in 2016. Shackleton (2013) estimates that average annual growth in U.S. MFP over the period 1870 to 2010 was between 1.6% and 1.8% which is about the same as average annual growth of per capita GDP over that period (1.8%) based on the Maddison Project (2013) data. If this is correct, the problem posed by Piketty’s inequality may be at least partially self-correcting. Per capita GDP growth increased substantially in Asia and somewhat less in Latin America between these two periods. His teaching and research interests include international trade, public policy, economic development, and ethics. Data collected by Maddison (World Economics, 2016) are in 1990 U.S. dollars while those of the World Bank (2017) are in 2010 U.S. dollars. Conservation practices such as no-till farming which can reduce soil erosion and chemical runoff, precision farming which allows more exact applications of chemical fertilizers and pesticides reducing the quantities required, and other environmentally benign management practices have been widely adopted around the world without significant sacrifices in total food production or farm incomes (Derpsch, Friedrich, Kassam, & Hongwen, 2010; Thakur, Kassam, Stoop, & Uphoff, 2016; U.S. Department of Agriculture, 2016). In any case, economic growth will remain important in the 21st century for at least two reasons. Average annual population, GDP, and per capita GDP growth rates are shown for selected countries for the period 1945 to 1975 in Table 6. You can be signed in via any or all of the methods shown below at the same time. In his important book on inequality, Thomas Piketty (2014) observes that economic growth “ . In the case of France, Italy, the Soviet Union, and Japan, much of this growth was driven by rebuilding after the destruction of the war years.
