Per-capita consumption
Per-capita consumption is a statistical measure that reflects the average consumption of resources per person in a specific population, highlighting the amount consumed annually by each individual. The term "per capita," derived from Latin meaning "by the head," is commonly used to report on various consumption statistics, including food, energy, and other resources. For instance, in the United States, the per-capita meat consumption is approximately 270.7 pounds per person per year, significantly higher than the global average of 102.5 pounds. This metric allows for comparisons over time and between different countries, revealing disparities in consumption patterns.
Per-capita consumption also sheds light on broader issues of resource usage, particularly between developed and developing nations. For example, in 2008, developed countries exhibited per-capita consumption rates thirty-two times higher than those in developing regions, raising concerns about sustainability and resource depletion as populations grow and consumption patterns shift. It is important to distinguish per-capita consumption from economic measures such as GDP per capita, which evaluates economic output per person, as these metrics serve different analytical purposes. Overall, understanding per-capita consumption is crucial for assessing global resource distribution and the potential impacts of changing consumption behaviors.

Per-capita consumption
Per-capita consumption is a statistical measure of a country’s consumption of resources per person. In Latin, capita means “head.” Per capita, therefore, means “by the head” or “per person.” The term per capita is typically used for reporting information about a population.
Per-capita consumption can measure a country’s consumption of everything from meat to oil. It usually determines the total amount of something consumed per person per year in that country. This figure can then be used to compare with the consumption from other years or to compare with the consumption of other countries. Per-capita consumption can also measure a country’s overall rate of consuming all resources. This can be used to compare the overall consumption rates of different countries or to determine the world’s consumption rate. Per-capita consumption should not be confused with gross domestic product (GDP) per capita, gross national product (GNP) per capita, or gross national income (GNI) per capita.
Overview
Per-capita consumption measures a country’s usage of goods and services per person. For example, the US per-capita consumption of meat determines the number of pounds of meat (including red meat, poultry, fish, pork, and other meat products) each person in the United States consumes in a year. This figure stands at 327.8 pounds (149 kilograms) per person per year, which means that the average American consumes 327.8 pounds of meat each year. This rate can be compared to the meat consumption rates of other years. For instance, comparing multiple years will reveal whether US meat consumption per person per year has increased, decreased, or remained the same over time.
The US meat consumption rate can also be compared to other countries. For example, compared to the rest of the world, the United States has the second-highest per-capita meat consumption, behind only Portugal. India and Ethiopia have the lowest meat consumption at just 30 pounds (14 kilograms) and 17 pounds (7.7 kilograms), respectively, which is just a fraction of the meat the average American consumes in a year. Additionally, a world average meat consumption per person can be determined. Comparing this average to the US consumption rate reveals that the average American consumes significantly more meat than the average person elsewhere in the world.
Per-capita consumption can also be used to determine the overall rate that a country consumes all resources. These statistics can be used to compare countries or regions of the world. For example, in the early twenty-first century, developed countries, including those in North America and Western Europe, had a relative per-capita consumption rate that was thirty-two times higher than developing nations, such as those in Africa. In 2022, the world population exceeded 8 billion people, and developing countries held about 6.6 billion people.
These statistics suggest that the world may be in danger. Developing countries focus on increasing standards of living, which leads to increasing per-capita consumption rates. For example, China's growing population of over 1.4 billion is exponentially higher than that of the United States. As China's consumption rate increases to match that of the US, the world’s resources are strained. The world’s oil and metal consumption, for example, increased significantly in the first two decades of the twenty-first century. As other developing nations follow China in increasing their consumption rates, the world’s resources are continually depleted.
Related to this problem is the notion that many people in developing countries emigrate to developed countries for a better life. In other words, these people move from a low-consumption to a high-consumption country. Consequently, developed countries’ populations would increase, and the world’s consumption rates would eventually rise, leading to overconsumption and putting further strain on resources.
Per-capita consumption is not to be confused with gross domestic product (GDP) per capita, gross national product (GNP) per capita, or gross national income (GNI) per capita. GDP represents the total yearly production of a country’s economy. Therefore, GDP per capita measures a country’s total economic output per person. To determine a country’s GDP per capita, the GDP is divided by the country’s total population. In 2023, the United States’ GDP was $27.36 trillion, and the country’s total population was 335 million. This means that the United States’ GDP per capita was $73,600 in 2023. Comparing this GDP per capita to the rest of the world, the United States is one of the most prosperous countries.
As with GDP per capita, GNP per capita also measures a country’s economic output. Unlike GDP, however, GNP also measures the income of the country’s residents and businesses. Specifically, GNP measures the income and the output of everything that is manufactured both domestically and abroad. GNI is similar to GNP, except that it also measures any product taxes that are not included in the output.
