The number of deaths registered in the UK over one week has fallen below the five-year average for the first time since mid-March.
More than 80% of local authorities in Great Britain have also seen death rates fall to normal levels.
The decrease reflects a decline in coronavirus-related deaths, official data shows.
Of 10,681 deaths registered in the week up to 19 June, 849 (8%) mentioned coronavirus.
This is the lowest number of coronavirus deaths registered since the week lockdown was announced.
The total number of deaths registered in the week up to 19 June was eight below the five-year average for that week and the lowest figure since the week of 13 March.
BBC analysis of the figures shows that more than four out of every five local authorities in Great Britain have seen death rates fall back to or below normal levels.
At the peak of the epidemic in mid-April, only 10 of 187 local authorities were in this range, with nearly 160 seeing registered deaths significantly above the five year average in that area.
While the figures are not yet down to the levels seen in the weeks before the coronavirus epidemic started, nearly every local authority in Great Britain has seen the number of deaths fall substantially from the epidemic’s peak in mid-April.
