Wage inequality has decreased in about two-thirds of all countries since 2000, says a new report released by the International Labour Organization (ILO) on Thursday.

Despite this positive trend, significant wage inequality persists worldwide.

‘The Global Wage Report 2024-25: Is wage inequality decreasing globally?’ finds that since the early 2000s, on average, wage inequality, which compares the wages of high and low wage earners, decreased in many countries at an average rate that ranged from 0.5 to 1.7 percent annually, depending on the measure used.

The most significant decreases occurred among low-income countries where the average annual decrease ranged from 3.2 to 9.6 percent in the past two decades.

Wage inequality is declining at a slower pace in wealthier countries, shrinking annually between 0.3 and 1.3 percent in upper-middle-income countries, and between 0.3 to 0.7 percent in high-income countries.

Moreover, even though wage inequality narrowed overall, decreases were more significant among wage workers at the upper end of the pay scale.

Real wages rose globally but regional differences persist

The report also finds that global wages have been growing faster than inflation in recent times.

In 2023, global real wages grew by 1.8 percent with projections reaching 2.7 percent growth for 2024, the highest increase in more than15 years.

Such positive outcomes mark a notable recovery when compared to the negative global wage growth, of -0.9 percent, observed in 2022, a period when high inflation rates outpaced nominal wage growth.

However, wage growth has been uneven across regions, with emerging economies experiencing stronger growth than advanced economies, the report finds.

While advanced G20 economies registered a decline in real wages for two consecutive years (−2.8 percent in 2022 and −0.5 percent in 2023), real wage growth remained positive for both years in emerging G20 economies (1.8 percent in 2022 and 6.0 percent in 2023).

Regional wage growth patterns varied considerably

Wage workers in Asia and the Pacific, Central and Western Asia, and Eastern Europe experienced their real wage increases at a faster rate than those in other parts of the world, according to the report.

"The return to positive real wage growth is a welcome development," said ILO Director-General, Gilbert F. Houngbo.

"However, we must not forget that millions of workers and their families continue to suffer from the cost-of-living crisis that has eroded their living standards and that wage disparities between and within countries remain unacceptably high."

Persistent wage inequality

Despite recent progress, high levels of wage inequality remain a pressing issue.

The report shows that globally, the lowest-paid 10 percent of workers earn just 0.5 percent of the global wage bill, while the highest-paid 10 percent earn nearly 38 percent of this wage bill.

Wage inequality is the highest in low-income countries, with close to 22 percent of wage workers there classified as low-paid.

Women and wage workers in the informal economy are more likely to be among the lowest paid.

This finding reinforces the need for targeted actions to close wage and employment gaps and ensure fair wages for all wage workers.

Wage inequality is relevant in all countries and regions. Globally, however, one in every three workers is a non-wage worker.

In most low- and middle-income countries the majority are self-employed workers, who can only find opportunities to earn a living in the informal economy.

It is for this reason that the report broadens its analysis to include the self-employed in the case of low- and middle- income countries.

As a result, measured labour income inequality increases significantly in these regions, as compared to that measured based only on wages from wage workers.

"National strategies to reduce inequalities require strengthening wage policies and institutions," says Giulia De Lazzari, ILO Economist and one of the main authors of the report.

"But equally important is to design policies that promote productivity, decent work and the formalization of the informal economy."

Strengthening wage policies to reduce inequality

The study emphasizes the need for targeted policies to foster inclusive economic growth.

The report concludes that reducing wage inequality requires both strong wage policies and structural support for equitable growth. By addressing these challenges countries can make real progress toward reducing wage gaps and promoting fair, sustainable, economic growth for workers worldwide.

Key ILO recommendations include:

Setting wages through social dialogue: wages should be set and adjusted through collective bargaining or agreed minimum wage systems involving governments, workers and employers.

Taking an informed approach: wage-setting should take into account both the needs of workers and their families and economic factors.

Promoting equality, and equal opportunity of treatment and outcomes: wage policies should support gender equality, equity and non-discrimination.

Using strong data: decisions should be based on reliable data and statistics.

Addressing root causes of low pay: national policies should reflect each country’s specific context and address the causes of low pay such as informality, low productivity and the under-valuing of jobs in sectors such as the care economy.
