Chinese and Indian ethnic group workers have higheraverage earnings than their white Britishcounterparts, the first detailed official figures show.
But the data on the ethnicity pay gap, showed allother ethnic groups have lower wages than whiteBritish workers.
The Office for National Statistics said employees inthe Bangladeshi ethnic group have the largest pay gap, earning 20% less than white Britishemployees.
On average, ethnic minorities earn 3.8% less than white ethnic groups.
In 2018, employees from the Chinese ethnic group earned 30.9% more than white Britishemployees.
Hugh Stickland, senior ONS analyst, said: "Overall, employees from certain ethnic groups suchas Indian and Chinese, have higher average earnings than their white British counterparts.
"However, all other ethnic groups have average wages lower than for white British employees, with employees from the Bangladeshi ethnic group having the largest pay gap.
"However, once characteristics such as education and occupation are taken into account, thepay gap between white British and most other ethnic groups becomes narrower, thoughsignificant differences still remain."
The data - based on median gross hourly earnings between 2012 and 2018 - shows that theChinese ethnicity group is the highest paid, receiving £15.75 an hour in 2018.
That group is followed by the Indian ethic group - which earns £13.47 an hour - andmixed/multiple ethnicity group, with a £12.33 hourly pay rate.
The median pay of the white British group was £12.03. The Bangladeshi group had the lowestmedian hourly pay of £9.60 with the second-lowest paid group being of Pakistani origin at £10 an hour.
"The harsh reality is that even today race still plays a real role in determining pay," saidFrances O'Grady, general secretary of the TUC.
"Ministers must take bold action to confront inequality and racism in the labor market. Theobvious first step is to introduce mandatory ethnicity pay gap reporting without delay," shesaid.
The government has already introduced mandatory reporting on the gender pay gap - whichstands at 9.6% in favor of men - and the ONS data also shows discrepancies in male and femaleearnings in the ethnic groups.
The Chinese and Indian groups, which both have the highest rate of hourly pay, were amongthose with the biggest gender gaps.
Chinese men on average earned 19.1% more than women and Indian men earned 23.2% morethan women.
But women in the Bangladeshi ethnic group earn more than their male counterparts - with a 10.5% gap.
The ONS said, though, that the sample size for the Bangladeshi group was smaller andsusceptible to inaccuracy compared with other ethnic groups.
The ONS says that where someone is born can have an influence on how much they are paid.
"By comparing those who were born in the UK and those who were not, it may give us an ideaof what sort of effect having a UK education and the higher likelihood of speaking English as afirst language may have on those from an ethnic minority background," the ONS said.
It found those in the Bangladeshi ethnic group - who had been born in the UK - earned 8% lessthan white British employees. But for Bangladeshi employees born outside the UK the gap was 26.8%.
When taking other factors into account, such as education, UK-born employees in the Indianand Chinese ethnic groups do not have pay gaps that are "statistically different" from the UK-born white British employees, the ONS found.
For example, almost a third of workers in the Indian ethnic group work in professional roleswhich means they tend to be higher-paid.
