The Economic Impacts Of Rapid Population Growth
It’s easy to see why some people worry about the rate of population growth in developing countries. If we look at the world’s low-income countries, we see that the population of more than 2 billion is growing at a rate that is estimated to double every 31 years. How do we deal with so many people? The following statement broadly describes the content of the planned thought process:
“At the end of each day, the world has two hundred thousand more people than the day before; a million and a half more every weekend; An additional eighty lakhs at the end of each year … Humanity, now doubling its numbers every twenty-five years, is under its own attack; Economists have called it the “Malthusian trap,” which most clearly expressed our biological problem: population growth will outstrip the food supply. Philip Appleman, ed. and Background, Critique (New York: Norton, 1976), xi
But what should we say about such a statement? If the world’s population continues to grow at the growth rate of the past 50 years, economic growth is unlikely to translate into improvements in average living standards. But population growth rates are not constant; It is influenced by other economic forces This section begins by discussing the relationship between population growth and income growth, then moves on to explain the sources of population growth in low-income countries, and concludes by discussing the Malthusian caution suggested in the quote above.
At a simplified level, there is an obvious relationship between population growth and per capita income growth. Finally, per capita income is equal to total income divided by population. The growth rate of per capita income is equal to the difference between the growth rate of income and the growth rate of population. The annual growth rate was 3.3 percent. Its population growth rate during this period was 3.2%, so the per capita growth rate is only 0.1%. A slower rate of population growth will leave Kenya with more impressive growth in per capita income at the same rate of GDP growth. This means that if developing countries want to increase per capita income relative to developed countries, they must limit population growth.

Figure 19.2 “Population and Income Growth, 1975–2005” shows population growth rates versus per capita growth rates for 1975–2005 in more than 100 developing countries. We do not see a simple relationship. Many countries have experienced rapid population growth and negative changes in real GDP per capita, but others have had relatively rapid population growth but faster growth in GDP per capita. Obviously, growth in per capita income is greater than Slowing population growth But the challenge at the forefront of this segment remains: Can the world continue to support a population that is growing rapidly — that is, doubling at regular intervals?
A scatterplot of population growth rates versus per capita gross national product growth rates for the period 1975–2005 shows that there is no systematic relationship between population growth rates and income.
. It became one of the most enduring works of its time. Malthus’ fundamental argument was that population growth inevitably collides with income.
Diminishing returns mean that adding more labor to a given land increases output, but by smaller and smaller amounts. Ultimately, Malthus concluded that the increase in food production would be too small to sustain the number of consumers of these products. As population goes unchecked, the number of people will eventually exceed the Earth’s ability to produce enough food, creating an inevitable Malthusian trap where the world’s population can no longer meet the population’s food needs, and hunger will be the main problem with population growth. , where the world is no longer able to meet the population’s food needs, and hunger becomes the main factor hindering population growth.

The Malthusian trap is shown in Figure 19.3 “The Malthusian Trap”. The total amount of food required can be determined by multiplying the population at any given time by the amount of food required for the survival of one person. As the population accelerates, the demand for food grows faster and faster, as seen in the curve called “Food Demand”. According to Malthus, the food produced increases in constant quantity in each period; Its production is represented by an upward sloping straight line called the food producing demand for food eventually outstrips food production and the Malthusian network comes in time
If the population grows at some exponential rate, the amount of food needed will increase exponentially, but Malthus believed that food production can only increase by a constant amount in each period. In maltose lattices, as shown here in T
What happens in the maltese trap? Obviously, the “food required” curve did not provide enough food to support population growth. Instead, people starved and the population began to grow exponentially, as reflected by the “food yield” curve. Hunger becomes the limiting force of the population; The population lives on the edge of survival For Malthus, the long-term destiny of man was a standard of living that was sufficient for survival.
Fortunately, Malthus’s predictions did not match the experience of Western society in the 19th, 19th, and 20th centuries. The weakness of his argument is that it does not take into account the productivity gains that can be achieved through increased physical capital and new technologies in agriculture. Increases in the amount of capital labor in machinery, improved seeds, irrigation, and the use of fertilizers allowed a large increase in agricultural production along with the supply of labor. Agricultural production in the United States has grown rapidly over the past two centuries, in contrast to the decline in productivity that Malthus expected. Productivity increased

Malthus was also wrong about the relationship between population growth and income, he believed that any increase in income would promote population growth. But the law of demand tells us that the opposite can be true: Higher incomes reduce population growth The primary cost of having children is the opportunity cost of the time parents spend raising them—higher incomes increase this opportunity cost. Higher incomes increase the cost of having children and reduce the number of children people want, thus slowing population growth.
Panel (a) of Figure 19.4, “Income Levels and Population Growth,” shows fertility rates in low-, middle-, and high-income countries for 2000–2005. We find that the higher the income level, the lower the birth rate. Fewer births mean slower population growth. In panel (b), we see that population growth rates in high-income countries have been much slower than in middle- and low-income countries over the past 30 years.
Panel (a) shows that low-income countries had significantly higher total fertility rates (births per woman) than high-income countries during 2000–2005. In panel (b), we see that low-income countries are much more likely
