Standard of living and quality of life are often referred to in discussions about the economic and social well-being of countries and their residents, but what is the difference between the two? The definitions of these terms can be difficult to tease apart and may overlap in some areas, depending on whom you ask. It's more than just a matter of semantics; in fact, knowing the difference can affect how you evaluate a country where you might be looking to invest some money.

Tutorial: Economic Indicators to Know

Standard of Living
Standard of living generally refers to the level of wealth, comfort, material goods and necessities available to a certain socioeconomic class, in a certain geographic area. An evaluation of standard of living commonly includes the following factors:

When you think about standard of living, you can think about things that are easy to quantify. We can measure factors like life expectancy, inflation rate and the average number of paid vacation days workers receive each year, for example.

Standard of living is often used to compare geographic areas, such as the standard of living in the United States versus Canada, or the standard of living in Milwaukee versus New York City. If you live in a particular country, a certain number of vacation days per year will be the norm. In the United States, it's 10 to 20 days while in Denmark it's 31. Some companies within each country may be more or less generous, but one practice prevails.

Standard of living can also be used to compare distinct points in time. For example, compared to a century ago, the standard of living in the U.S. is considered to have improved greatly; the same amount of work buys a larger quantity of goods, and items that were once luxuries, such as refrigerators and automobiles, are now widely available. Also, leisure time and life expectancy have increased and annual hours worked has decreased.

One measure of standard of living is the Human Development Index (HDI), developed in 1990 by the United Nations. It considers life expectancy at birth, adult literacy rates and per capita gross domestic product (GDP) to measure a country's level of development. (For related reading, see What is GDP and why is it so important?)

Quality of Life
Quality of life is more subjective and intangible. The United Nations' Universal Declaration of Human Rights, adopted in 1948, provides an excellent list of factors that can be considered in evaluating quality of life. It includes many things that citizens of the United States and other developed countries take for granted, but that are not available in a significant number of countries around the world. Although this declaration is 60 years old, in many ways it still represents an ideal to be achieved, rather than a baseline state of affairs. Factors that may be used to measure quality of life include the following:

  • freedom from slavery and torture
  • equal protection of the law
  • freedom from discrimination
  • freedom of movement
  • freedom of residence within one's home country
  • presumption of innocence unless proved guilty
  • right to marry
  • right to have a family
  • right to be treated equally without regard to gender, race, language, religion, political beliefs, nationality, socioeconomic status and more
  • right to privacy
  • freedom of thought
  • freedom of religion
  • free choice of employment
  • right to fair pay
  • equal pay for equal work
  • right to vote
  • right to rest and leisure
  • right to education
  • right to human dignity

Comparing the Two
When people think about their own standard of living, the amount of money they bring in might be the first thing that comes to mind. If their income decreases, through job loss, for example, they might consider their standard of living to be decreasing along with it, however is this the case? If you consider the other factors that make up standard of living, then chances are your overall standard of living is still quite good, despite your present lack of income. For example, if you have a good chance of securing another quality job, your country's economy is generally strong, you still have access to health care, and if the cost of goods and services is reasonable enough that you can more or less get by in the meantime, until you find a new job, then you're doing all right. (To reduce health care expenditures, read Fighting The High Costs Of Health care and 20 Ways To Save On Medical Bills.)

Standard of living is somewhat of a flawed indicator, however. Looking at our earlier list, while the United States, for example, might be considered to rank highly in all of these areas, most people would agree that for some segments of the population, the standard of living in the United States is actually quite low. In East St. Louis, Ill., for example, the quality and availability of employment has historically been poor; environmental quality is below average for the U.S., the incidence of disease is high and life expectancy is also below average. According to the U.S. Census Bureau's 2000 census, the number of families living below the federal poverty level in East St. Louis was 35.1%, compared to a national average of 12.4%.

Similar to standard of living, what would be considered a good quality of life by one person, may not be considered as such by another. The earlier list of quality of life factors might also be considered to be a list of things the United States offers. "The Economist", for example, produces an index that attempts to rate the quality of life in various countries. Predictably, developed nations like Norway, Australia and Luxembourg come out on top and less-developed countries like Iraq, Afghanistan and Sudan come out on the bottom, according to "The Economist's" quality-of-life index. That said, there are certainly segments of the population, in countries like the United States, in which people don't have the right to marry whomever they choose, are discriminated against, are treated as guilty until proven innocent, do not have access to a meaningful and useful education and/or do not get equal pay for equal work.

The Bottom Line
The main difference between standard of living and quality of life is that the former is more objective, while the latter is more subjective. Standard of living factors such as gross domestic product, poverty rate and environmental quality, can all be measured and defined with numbers, while quality of life factors like equal protection of the law, freedom from discrimination and freedom of religion, are more difficult to measure and are particularly qualitative. Both indicators are flawed, but they can help us get a general picture of what life is like in a particular location at a particular time.
