What impact of Brexit on the UK economy can we see today?

Did the Brexit referendum in June 2016 and the actual Brexit in February 2020 have a negative impact on the UK economy? We can look at: Overall growth, employment and standard of living; Corporate and housing investment; Foreign trade; Capital inflows and exchange rate; The size of industry and financial services; Productivity gains, immigration and potential growth. There has been a deterioration since 2016 concerning: Growth and employment; Corporate and foreign direct investment; Industrial production; Productivity gains. But this deterioration is limited and does not concern construction, exports, non-resident purchases of financial assets, financial services or immigration. So the total cost of Brexit is actually very small.
