Household Consumption Reveals a Wide Economic Divide Across OECD Countries

A comparison of household consumption across the 38 member countries of the Organisation for Economic Co-operation and Development (OECD) highlights a striking feature of modern economies: average national wealth does not translate into the same level of consumption for every household.

The 2022 comparison shown in the graphic examines individual consumption at different points of the income distribution, from the lowest percentiles through the median and up to the highest-income groups. The figures are expressed in purchasing-power-parity (PPP) terms, allowing spending levels to be compared across countries while accounting for differences in price levels.

The data reveal substantial differences not only between countries but also within individual societies.

United States Stands Out at the Top

The United States occupies the highest position in the comparison, particularly among households toward the upper end of the consumption distribution.

The chart shows that American consumption rises sharply as income percentiles increase, with the highest percentile groups reaching substantially higher levels than the median household.

This illustrates the enormous spending capacity available to affluent American households.

At the same time, the lower end of the U.S. distribution sits much closer to the lower consumption levels observed in several other developed economies. The result is a wide spread between the country’s lowest and highest consumption groups.

Northern Europe Shows Strong Consumption Levels

Countries such as Luxembourg, Norway, Iceland and the Netherlands appear near the upper part of the comparison.

Their relatively high consumption levels reflect high living standards, strong household purchasing power and, in some cases, substantial national income generated by specialized industries or natural resources.

However, even these countries show considerable differences between lower-income and higher-income households.

This demonstrates that a high national standard of living does not eliminate inequality within a country.

Australia and Switzerland Also Rank Highly

Australia and Switzerland are positioned among the countries with relatively high consumption across much of the income distribution.

Switzerland is particularly notable because of its high living standards and strong purchasing power. Australia similarly combines relatively high household consumption with a developed economy and high average incomes.

But the distribution shown in the chart remains important: national averages can conceal major differences between households.

Germany and Other Western European Economies

Germany, Belgium, Austria, Denmark, Sweden and Finland occupy prominent positions in the comparison.

These countries combine developed industrial economies with extensive social protection systems and comparatively high living standards.

Their consumption distributions tend to be less extreme than the United States at the very top, although substantial differences still exist between lower- and higher-income households.

This suggests that economic equality cannot be understood simply by looking at average consumption.

The Median Provides a Different Picture

One of the most useful features of the comparison is its inclusion of the median.

The median represents the middle point of the distribution: half of the population lies below it and half above it.

This is often more informative than an average when examining inequality because extremely wealthy households can push the average upward.

For example, a country may have a very high average consumption level because a small proportion of households consume enormous amounts, while the typical household experiences a much more modest level.

Looking at multiple percentiles therefore provides a fuller picture.

Consumption Inequality Is Visible Within Countries

The biggest message from the data is the enormous distance between the lowest and highest consumption groups.

The chart tracks several points, including the 1st, 5th, 10th, 25th, median, 75th, 90th, 95th and 99th percentiles.

At the lower end, consumption levels are relatively close to one another in many countries.

At the upper end, however, the differences become much larger.

The richest households can have consumption levels several times greater than those of the median household.

Mexico, Costa Rica and Colombia Show Lower Levels

At the bottom of the comparison are countries including Mexico, Costa Rica and Colombia.

Their consumption levels are significantly below those recorded in the highest-ranking OECD economies.

This does not necessarily mean that people in these countries experience proportionally lower quality of life in every respect. Consumption measured in PPP dollars captures the purchasing value of goods and services, but it does not fully capture public services, household production, environmental quality or other dimensions of well-being.

Nevertheless, the figures provide an important indication of differences in material living standards.

Turkey and Chile Highlight the Middle Range

Türkiye and Chile occupy an intermediate position in the chart.

Both countries have developed substantially over recent decades, but their consumption levels remain below those of the richest OECD economies.

The distribution also shows that consumption inequality exists inside these countries, meaning national economic progress does not benefit every household equally.

Japan and South Korea Offer Interesting Comparisons

Japan and South Korea are among the major Asian economies represented in the OECD comparison.

Both have highly developed industrial and technological sectors, yet their household consumption distributions differ from those of the United States and several Western European countries.

Japan’s position is particularly interesting because the country has a very high level of economic development but has experienced prolonged periods of relatively slow growth and demographic change.

South Korea, meanwhile, has undergone an extraordinary transformation from a developing economy into a major global industrial and technological power.

Why PPP Matters

The chart uses purchasing power parity, or PPP, rather than simply converting household spending into U.S. dollars using market exchange rates.

This is important because the same amount of money can purchase very different quantities of goods and services in different countries.

For example, $1,000 of spending does not necessarily represent the same purchasing power in New York, Tokyo, Mexico City or Stockholm.

PPP attempts to account for these price differences, making international comparisons of consumption more meaningful.

Consumption Is Not the Same as Income

Another important distinction is that consumption should not be confused with income.

A household can consume more than its current income through savings accumulated in previous years, borrowing, transfers or other resources.

Similarly, a household with a relatively high income may save a substantial portion of its earnings and therefore have lower measured consumption.

Consumption can consequently provide a different perspective on living standards from income statistics.

The Richest Households Create a Dramatic Gap

The highest percentiles show just how concentrated consumption can become.

The 99th percentile represents households near the top of the distribution, rather than the average affluent household.

In several countries, consumption at this level is dramatically higher than at the median.

This is particularly visible in the United States, where the upper end of the distribution extends far beyond the middle of the population.

The pattern raises broader questions about wealth accumulation, taxation, access to financial assets and the distribution of economic gains.

Why the Data Matter for Policymakers

Understanding consumption distribution can help governments evaluate living standards and economic inequality.

GDP growth alone does not reveal how economic resources are distributed among households.

Two countries can have similar GDP per capita but very different distributions of consumption.

For policymakers, this distinction matters when designing social protection, taxation, healthcare, education and poverty-reduction programs.

A growing economy can still leave significant sections of its population with relatively low consumption capacity.

A Broader View of Economic Well-Being

The comparison also demonstrates why no single economic indicator can describe a country’s standard of living.

GDP measures economic production. Income measures resources received by households. Consumption measures what households actually use to obtain goods and services.

Each provides a different perspective.

The OECD has emphasized that measuring household economic well-being requires looking beyond aggregate economic statistics and considering how resources are distributed among people.
