Median Income vs. Average Income: Why the Middle Tells a Different Story

Two of the most quoted economic figures in the United States are median household income and average household income. They are often used interchangeably, but they tell very different stories about how Americans are faring. The median is the middle point of the income distribution—half of households earn more, half earn less. The average, or mean, adds up all incomes and divides by the number of households. Because a small number of very high earners can pull the average upward, the median is usually the more reliable indicator of a typical household’s financial situation. In 2024, the U.S. median household income was $83,730, while the average was significantly higher—a gap that reveals the long tail of income inequality in America.

Key Numbers

• 2024 U.S. median household income: $83,730
• Average household income: Significantly higher than the median due to wealthy outliers
• South Africa example: Average gross salary is ZAR 318,000, but median worker earns ZAR 72,000—a 4.4x gap
• Real median household income: Can remain deceptively stable even when economic or social conditions change
• Median income growth: Correlates with consumer confidence and is a democratic indicator of economic growth
• Primary U.S. source: U.S. Census Bureau, Income in the United States annual report
• Underreporting adjustment: One academic study found U.S. median gross household income was 15% higher in 2010 after correcting for underreporting

Explanation

The difference between median and average income comes down to arithmetic and the shape of the income distribution. The average is calculated by summing every household’s income and dividing by the total number of households. This means that a single billionaire can raise the average by a noticeable amount, even if most households earn far less. The median, by contrast, is found by lining up all incomes from lowest to highest and picking the one exactly in the middle. It is not affected by how far above the middle the richest households are—only by how many households are above or below that midpoint.

In a perfectly equal society, the median and average would be identical. But in the real world, income distributions are right-skewed: a large number of people earn modest incomes, while a smaller number earn very high incomes. This skew pulls the average above the median. The size of the gap between the two is a rough indicator of inequality. In high-inequality countries, the average can be several times the median. For example, in South Africa, the average gross salary is about ZAR 318,000 a year, while the median worker earns just ZAR 72,000—the average is 4.4 times the middle.

In the United States, the gap is smaller but still meaningful. The 2024 median household income of $83,730 represents the typical American household. The average household income is higher, but that higher figure describes almost no actual household—it is inflated by the top few percent of earners. This is why most economists and data journalists prefer the median when discussing how ordinary families are doing.

Definition

The median income is the income amount that divides a population into two equal groups: half have an income above that amount, and half have an income below it. It can be calculated for household income, personal income, or disposable income. The average income, also called the mean income, is the total income of a group divided by the number of people or households in that group. The table below summarizes the key differences.

How the Statistic Is Calculated

Calculating the median is straightforward but requires individual-level data. The steps are:

1. Collect income data for all households or individuals in the population.
2. Sort the incomes from lowest to highest.
3. If the number of observations is odd, the median is the middle value.
4. If the number is even, the median is the average of the two middle values.

The average is even simpler: add up all incomes and divide by the number of observations. However, because the average is so sensitive to extreme values, it can be misleading when the distribution is skewed. The U.S. Census Bureau calculates both measures from its annual Current Population Survey and publishes them in the Income in the United States report. The first two statistics in that report are median household income and its change from the previous year—a sign of how central the median is to official economic monitoring.

Why It Matters

The choice between median and average income has real consequences for how we understand economic progress. If policymakers or journalists report only the average, they may paint an overly rosy picture of economic growth that benefits only the top. The median, by contrast, stays anchored to the middle of the income distribution. As the Federal Reserve Bank of Minneapolis notes, median household income is a useful summary of overall economic well-being, but it can also be deceptively stable even when economic or social conditions change.

Growing numbers of one-adult households and rising household inequality aren’t fully captured by median household income.

Median income growth also correlates with consumer confidence and, in line with the median voter theorem, serves as a democratic indicator of economic growth. When the median rises, it usually means that a broad swath of the population is experiencing gains—not just those at the top.

Limitations of the Data

Both median and average income have limitations. The median does not capture what is happening at the very top or very bottom of the distribution. If the richest 1% see their incomes double while everyone else stays the same, the median will not move at all. Similarly, changes in household composition—such as more single-adult households—can affect median household income even if individual earnings are unchanged. The average, meanwhile, can be distorted by a small number of extremely high incomes, making it a poor measure of typical earnings.

Another limitation is underreporting. An academic study on Census income data found that when correcting for underreporting, U.S. median gross household income was 15% higher in 2010 than officially reported. This suggests that even the median may understate true economic well-being. Finally, comparisons over time require adjusting for inflation to produce real income, and comparisons across countries often use equivalised disposable income to account for household size and taxes.

Historical Data

The U.S. Census Bureau has published median household income annually for decades, making it one of the longest-running and most closely watched economic indicators. The real median household income—adjusted for inflation—has fluctuated with economic cycles, rising during expansions and stagnating or falling during recessions. The 2024 figure of $83,730 reflects a continuation of gradual growth, but the long-term trend shows that median income growth has often been slower than growth at the top of the distribution. This divergence is a key reason why the gap between median and average income has widened over time.

Year-over-Year Change

Each year, the Census Bureau reports not only the level of median household income but also its change from the previous year. This year-over-year change is one of the first statistics cited in the Income in the United States report. It is closely watched as a real-time indicator of how American households are faring. Because the median is less volatile than the average, its year-over-year changes tend to reflect broad-based shifts in the labor market, inflation, and government transfers rather than the fortunes of a few high earners.

10-Year Change

Over a decade, the difference between median and average income growth becomes even more pronounced. While the average can be lifted significantly by rapid income growth at the top, the median typically grows more slowly. This means that a 10-year comparison of average incomes may overstate how much the typical household has gained. For example, if the top 10% of earners see their incomes double while the bottom 90% see only modest gains, the average will rise substantially, but the median will barely move. This divergence is a central feature of rising income inequality in the United States.

Factors Behind the Trend

Several factors drive the gap between median and average income:

• Income inequality: A larger share of total income going to the top earners widens the gap.
• Household composition: More single-adult households can lower median household income even if individual wages rise.
• Top-earner growth: Rapid increases in executive pay, capital gains, and business income pull the average up without affecting the median.
• Inflation adjustments: Real median income can stagnate if nominal gains are eaten by inflation, while the average may still rise due to top incomes.
• Labor market shifts: Changes in the mix of full-time and part-time work, as well as industry composition, affect the middle of the distribution differently than the top.

National Comparison

The United States is not alone in having a gap between median and average income, but the size of the gap varies widely across countries. In low-inequality countries, the average and median are relatively close. In high-inequality countries, the average can be several times the median. The South African example—where the average salary is 4.4 times the median—is an extreme case, but it illustrates the arithmetic clearly. In the U.S., the gap is smaller but still significant, reflecting a long right tail of very high earners. International comparisons often use median equivalised disposable income, which adjusts for household size and taxes, to provide a more accurate picture of living standards across countries.
