Wage & Price Glossary

Average Annual Wage

Average annual wage is the mean yearly wage across the workers covered by the dataset. The OECD series used on this website presents wages on a full-time-equivalent basis, making the figures more comparable across economies with different working patterns. Because it is average, the value may be influenced by higher earners and should not be interpreted as the wage earned by a typical individual worker. It is also different from median wage, minimum wage and household income.

On this website: the value is displayed as a PPP-adjusted annual amount in constant prices.

PPP-Adjusted Wage

A PPP-adjusted wage converts national wage figures using purchasing power parities rather than ordinary market exchange rates. This reduces the effect of differences in local price levels and makes wages across economies more comparable. A PPP-adjusted amount is expressed using a common purchasing-power unit, but it is not the employee’s local-currency salary and should not be treated as an amount that can be exchanged directly at a bank.

Constant Prices

Constant-price figures remove the effect of general price changes over time by expressing wages using the purchasing power of a selected reference period. This makes historical wage values more suitable for comparing real wage direction. An increase in a constant-price wage generally represents growth beyond the price adjustment already applied to the series. It differs from a current-price or nominal amount, which reflects the money value reported in each individual year.

Nominal Wage

A nominal wage is the wage amount expressed in the prices and currency value of the period in which it was paid. It does not remove the effect of inflation. A nominal wage can increase even when its purchasing power changes very little. The main OECD wage series used on this website is presented in constant-price PPP terms rather than as a local nominal wage. Country pages do not display local nominal salaries.

Mean vs Median Wage

The mean is more affected by very high wages, while the median often gives a closer indication of the middle worker. This website uses an OECD average annual wage series and does not present the value as a median wage.

Gross vs Net Wage

Gross wage refers to earnings before personal income taxes and employee deductions. Net wage is the amount an employee receives after applicable deductions. The wage values shown on this website should not be interpreted as take-home pay because individual net income depends on tax rules, household circumstances, benefits and other deductions that are not included in the dataset.

This website does not calculate taxes or take-home salary.

Full-Time Equivalent

Full-time equivalent, often shortened to FTE, is a method of converting different working schedules into a comparable full-time workload. For example, two people each working half of a standard full-time schedule may together represent one full-time equivalent. Using an FTE basis reduces distortions caused by differences in part-time employment rates when average annual wages are compared across economies.

1-Year, 5-Year and 10-Year Change

These values show how much the PPP-adjusted average annual wage has changed over a selected period. The calculation compares the latest available value with the value one, five or ten years earlier.

Change (%) = ((Latest wage ÷ Earlier wage) − 1) × 100

If the corresponding year is missing: do not substitute a nearby year unless the product rule explicitly defines it.

Historical Peak

Historical peak is the highest PPP-adjusted average annual wage recorded within the available series for an economy. The peak is based only on the years contained in the dataset and does not imply that the value is the highest wage ever earned in that country. Economies with shorter historical coverage may have a less complete peak comparison.

Shown alongside this metric: peak value and peak year.

Change From Peak

Change from peak compares the latest available wage with the highest recorded wage in the country’s available series. A value of −3% means the latest wage is approximately 3% below its recorded historical peak. A value of 0% means the latest value is also the highest available value.

Change from peak = ((Latest wage ÷ Historical peak) − 1) × 100

Growth Index

A growth index shows the relative movement of wages rather than their monetary values. The first common year in the selected comparison range is set to 100. Later values show how much each country’s wage has changed from that starting point. An index of 112 indicates that the wage is 12% above the starting value.

Growth Index is not a wage amount.

• Australia: 115 — from the common starting point, +15%
• Germany: 108 — from the common starting point, +8%

Latest Available Year

The most recent year for which a valid observation is available for a country and metric. Different economies may have different latest available years. When this happens, the website displays each year clearly rather than presenting the values as though they refer to the same period.

Latest Common Year

The latest common year is the most recent year for which every country included in a comparison has a valid value. It is useful when countries need to be ranked or compared on a strictly consistent time basis. It may be earlier than the latest available year shown on an individual country page.

Purchasing Power Parity (PPP)

Purchasing power parity is a conversion method designed to compare the purchasing power of currencies across economies. It reflects how much currency is required to purchase a comparable set of goods and services in different locations. PPP differs from a market exchange rate, which is determined through currency markets and may fluctuate for reasons unrelated to domestic consumer prices.

Comparative Price Level

A comparative price level shows how the price of a comparable group of goods and services differs between economies after purchasing power parities and market exchange rates are considered. On this website, the United States is the reference economy with a value of 100. The result is an index, not a currency amount and not an inflation rate.

Price Level Index

A price level index is a relative measure used to compare prices between economies in a selected year and consumption category. A value above 100 indicates a price level above the United States benchmark, while a value below 100 indicates a price level below that benchmark.

• 120 = 20 index points above the U.S. benchmark
• 85 = 15 index points below the U.S. benchmark
• 100 = equal to the U.S. benchmark

United States = 100

All consumer price-level values on this website use the United States as the reference economy. A U.S. value of 100 provides a common comparison point for every other economy in the selected year and category.

Index Points

Index points describe the arithmetic difference between two index values. If Australia has a price-level value of 108 and Germany has a value of 95, Australia is 13 index points higher than Germany.

108 − 95 = 13 index points

Overall Price Level

Overall price level is the broadest consumer price measure presented on the website. It represents actual individual consumption rather than one specific spending category. It provides a useful general comparison, but it does not mean that every product or service is more or less expensive by the same amount.

Also published as: Actual individual consumption. This site labels it Overall.

Consumer Price Category

A consumer price category isolates a particular type of household consumption so that price patterns can be compared more precisely. A country may have a relatively high housing index but a lower clothing or healthcare index, so the overall value should not be assumed to represent every spending area.

• Overall
• Food
• Clothing
• Housing
• Health
• Transport
• Recreation
• Restaurants & Accommodation

Price Level vs Inflation

A country can have a high price level and low inflation, or a lower price level and high inflation. The consumer price data on this website compares price levels; it does not report an inflation rate.

Price Level vs Cost of Living

Comparative price-level data is useful for understanding broad differences in consumer prices, but it is not a personalized cost-of-living calculation. Actual household expenses depend on location, housing arrangements, consumption habits, taxes, public services and household size. The index should therefore be interpreted as a standardized economic comparison rather than an estimate of a particular person’s monthly budget.

Missing Value

A missing value means that the selected dataset does not provide a usable observation for the requested country, year or category. Missing data is displayed as a dash rather than as zero.

Price data: do not automatically use another year.

Wage trends: do not draw a zero-value point or invent an observation.

Base Year and Price Base

A base year or price base provides the reference price structure used to express constant-price values. It allows values from different years to be compared after general price changes have been accounted for. The base period is part of the dataset methodology and should not be confused with the observation year shown beside a wage value.

Organisation for Economic Co-operation and Development

OECD

The OECD is an international organisation that publishes comparable economic and social statistics. This website uses OECD datasets for average annual wages and comparative consumer price levels. The site reorganizes and explains those observations but does not represent or speak on behalf of the OECD.
