We get our word “demographics” from the Greek for “people” (demo) and “measurement” (metry) (graphics). Population growth and decline are perennial topics of inquiry for economists.
Books by Malthus and others on the subject of population growth are frequently found in economics textbooks. As the economy recovers from the Great Recession and the financial crisis, policymakers shift their attention from cyclical to structural factors.
Because policymaking is beginning to follow a more predictable cycle, the question of what constitutes “normal” actually is. A proper response necessitates insight into the factors that propel and shape the economy. This makes no sense except for those who are well-versed in the country’s demographics.
The natural interest rate, unemployment over the long run, housing market tendencies, and demand for financial assets may all be affected by demographic shifts.
There may be repercussions for currencies and current account surpluses if national population growth rates are inconsistent. Monetary and fiscal policymakers will need a global perspective to meet the challenges posed by demographic shifts.
Demographic Changes and Law
In this discussion, we’ll examine how demographic shifts in recent decades have reshaped the law. Clearly, the Federal Open Market Committee and the Federal Reserve System do not share my views (FOMC).
Statistical evidence suggests a population shift may have taken place. Due to high mortality rates, global population growth slowed to a trickle until the early 18th century.
Improved medical care, public health measures, and dietary standards have contributed to a declining death rate1 over the past few decades. The overall population decline was mirrored by a decrease in the birth rate.
Due to rising opportunity costs and the high cost of raising and educating children, the number of two-parent and one-child households in the United States is on the rise. Fewer people’s lives required them to have big families as they left the countryside for the cities.
Cultural attitudes shifted as more people gained access to and used birth control. Shortly after World War II, members of the “baby boom” generation began having children in the United States, leading to a second surge in births.
The current fertility rate in the United States is 1.88 children per woman (United Nations 2017: 807). The United Nations has set a goal of 2.1 children per woman to ensure population stability, but current fertility rates are well below that. The figure in 1900 was larger than 3.2.
These shifts have contributed to an increasingly elderly and frail population in the United States. Those born in the modern era have a life expectancy nearly 30 years higher than those born in 1900. The current median age in the United States is nearly 38 years old, nearly ten years older than in 1970.
The United Nations estimates that by 2050, the median age in the United States will be 42, with most of the population being 65 and older. Most U.S. residents were young adults between 15 and 64 in 1970.
Predicted Population Decrease
As the world’s population ages and fertility rates remain stable, demographers forecast a slowing global population growth rate. Sixth, it averaged 2% between 1965 and 1969 but only 1.2% between 2010 and 2015.
In recent decades, natural increase has been the primary factor in expanding the United States population. However, according to the UN, nearly two-thirds of the growth between 2015 and 2050 will result from net migration. 7
Though countries all over the world are feeling the effects of an ageing population, the United States is falling behind because of this trend (Bloom and Canning 2004: 18).
As a result of its ageing population, Japan has seen a decline in its working-age population over the past five years. In Japan, nearly 47 is the median age. (United Nations, 2017:415).
The fertility rate in Europe has been dropping precipitously in recent decades (United Nations 2017: xxvii). Since the late 1980s, China’s working-age population growth has slowed; the country’s aging population is partly attributable to China’s previous one-child policy (United Nations 2017: 191; Peng 2011). From the low 20s in 1970 to the mid-30s in 2015, China has seen a dramatic increase in the onset of middle age.
In many low and middle-income countries, the demographic transition, characterized by young, rapidly growing populations and rising labor force participation rates, is just getting started. From 2010-2015, India’s total population grew by an annual average of 1.2%, and the country’s median age increased to almost 27.
Within the next seven years, India is expected to become more populous than China. This pattern is expected to persist until 2050. A large portion of the predicted multi-billion-person increase in global population by 2050 can be attributed to Africa’s high fertility rate.
Implications of Global Demographic Trends
If policymakers in the United States do not give serious thought to the implications of global demographic trends, the future of the American economy is at risk. You have some say in how seriously you wish to take the consequences.
Another important point to look at is the implications of these demographic changes for the American economy, specifically the job market and GDP growth.
As a result of demographic changes like the declining birthrate and the rising retirement population, the median age is forecasted to rise. As a result of the change, the natural unemployment rate and potential output growth are expected to slow.
There are too many moving parts and uncontrollable variables in consumer and business behaviour for us to accurately predict the size and timing of these effects. Business cycles and the transmission of monetary policy may be affected by demographic shifts.
The relationship between structural changes and business cycles is important for financial policymakers to keep an eye on. Government budget planners need help adjusting for population growth or decline because of the complexity involved.
Final Words
A rising debt-to-GDP ratio is a potential outcome of widening budget gaps, which could increase interest rates and dampen the incentive to make productive investments.
Preventative measures can help the economy weather the storm of aging and other demographic shifts. These policies aim to contribute to a more equitable distribution of economic resources by boosting productivity and employment.
