The sixth form student told the prime minister how he had been hassled by police when with a group from minority ethnic backgrounds and seeing the officers ignore a larger group of white people.
But critics of the Prime Minister have accused her of using the data for "political point scoring".
Theresa May will challenge society to "explain or change" disparities in how people from different ethnic backgrounds are treated, as the Government publishes the results of a wide-ranging audit of public services.
■ Of all applicants shortlisted for NHS jobs in England, white candidates were more likely to be appointed - some 18 per cent of whites shortlisted got the job compared with 11 per cent of ethnic minorities.
The new site, available later today, contains thousands of statistics covering more than 130 topics in areas including employment, health, education, and criminal justice.
But there are some areas where whites suffer worse than minorities - with white children more likely to claim free school meals and white patients worse hit by mental health problems.

Attempting to relaunch that agenda, May will publish the findings of a "Race Disparity Audit", which will not, she says, come as a surprise to many.
In her statement on the review, May will reportedly say: "People who have lived with discrimination don't need a government audit to make them aware of the scale of the challenge".
"This audit means that for society as a whole - for government, for our public services - there is nowhere to hide".
She will say "these issues are now out in the open" and that the collection of data provides "definitive evidence" of the challenges the United Kingdom still faces to "build a country that works for everyone".
Cracking her whip on the shocking race inequality in the UK, Prime Minister Theresa May has warned business leaders, government and institutions that they must ensure that race is never a barrier to people achieving their goals.
"Britain has come a long way in my lifetime in spreading equality and opportunity. We must now work together as a society to find solutions".
