No, the Telegraph article you showed does not say that:

Despite claims that forces are struggling to cope, analysis of Home Office data shows that in 1961 there were 807 people for every police officer in England and Wales, whereas the most recent figures, released earlier this month in a House of Commons briefing paper, show that there are now 462 people for every officer.
Police numbers rose during the 1980s and early 1990s, before falling to a 10-year low at the end of the 1990s and rising sharply in the early 2000s.
They have been dropping again since 2009, when they had reached a high of 141,647.
The crime levels of 1961 and today are markedly different. In 1961, 806,900 crimes were committed whereas ONS data shows that 5.2 million crimes were recorded this year, a 13 per cent rise from the year before.
So a bit less than twice the number of police officers compared to 1961 but more than 5 times the level of crime.

The size of the total police workforce in England and Wales has fallen below 200,000 for the first time in more than a decade.
Forces employed 198,228 personnel - including officers, civilian staff and PCSOs - at the end of September.
The tally fell by 6,201, or 3 per cent, year-on-year - while it has dropped by more than 25,000 compared to a decade earlier.
It is the first time the total workforce figure has dipped below 200,000 since 2003.
