Economists use various measures to assess economic growth, including GDP, consumption patterns, wages, life expectancy, and healthcare quality. Higher GDP and wages often indicate a healthier economy, while longer life expectancy and better healthcare access represent longer-term growth.
Economists measure the economic growth of an area or nation for a variety of reasons, including investment potential, to assess the living standards of places, and to project future financial growth. There are several ways to measure economic growth, including calculating gross domestic product and studying consumption patterns. Other measures of economic growth include a variety of assessments of social conditions. These may include life expectancy, the quality of health care and the general level of wages.
Some researchers consider gross domestic product as one of the main measures of economic growth. Abbreviated as GDP, this measurement is a calculation of an economy’s total annual value of the production of goods and services for a given year. GDP can be thought of in two ways: the calculation is both the total amount of money spent buying products and that derived from the creation of products. High GDP often means that a country is economically sound and that many of its citizens are thriving.
An economy’s minimum wage is one of many earnings-based measures of economic growth. Other general wage measurements include the worker’s hourly wage, the annual wage for specific industries, or the average annual wage for the entire population. Similar to GDP, higher average and minimum wages often mean a relatively healthier economy.
Another economic measure is the rate of consumption of goods, which includes calculating the total number of products purchased during a given period of time. This formula may not be as reliable as other measures of economic growth because several factors can cause consumption to fluctuate. For example, sometimes consumption increases because citizens are wealthy and able to buy more, while other times consumption increases because the prices of goods and services have fallen.
An increase in life expectancy, or the average number of years lived per person, is a measure of longer-term economic growth. Areas with longer life expectancies tend to have wealthier populations who have continued access to food, clean water and healthcare. Life expectancy rates usually change more slowly than other forms of growth measurement because it could take a long time to increase the health of an entire population.
In relation to life expectancy, access to quality healthcare can be used as a more abstract measure of economic growth. Total spending on health care tends to increase along with rising GDP and income levels. Higher healthcare expenditure may coincide with better quality of healthcare and increased life expectancy, representing and indicating a longer lifespan in the future.
