Data on asylum in the UK here. Says updated for 2023, but most stats seem to still be 2021 ish, which will not reflect any Ukrainian applications.

Some of the questions from this thread:
'In 2021, the top five most common countries of nationality of people who applied for asylum in the UK were Iran, Iraq, Eritrea, Albania and Syria'.
'When compared against EU+ countries, in 2021 the UK ranked 6th in the absolute number of people to whom it gave protection, comprising asylum seekers and resettled refugees'.
'Looking at all people who sought asylum from 2010 to 2020, 68% were male, and 65% of all grants of asylum or other leave at initial decision were to men or boys'.
'Of all refugees resettled in the UK from January 2010 to December 2021, around 70% were Syrian citizens'.
The % of applications being refused/granted is more complicated because obviously it's subject to variables like country of origin. For example, might be high in a year when most applications were from Syria and lower in a year when most applicants were not fleeing obvious war zones.
