The population of Birmingham has risen four and a half times faster than the rate of new housing over the last decade.
Exclusive analysis of official data by the Birmingham Post shows that the number of people living in the city rose by 98,984 between 2004 and 2014.
At the same time, the net number of new dwellings rose by just 22,000 in the decade to March 2015.
That means there are 4.5 extra people in Birmingham for every one extra home.
Coventry's population has grown by 39,254 while the net number of new dwellings has risen by 9,340.
That is 4.2 extra people for every extra home. In Sandwell, the figure is 3.0 while in Walsall it is 2.5.
In other parts of the region, however, the pressure is far less or non-existent.
Wolverhampton has 2.0 new homes for every extra person, Solihull has 1.8 and Dudley has 1.3.
The figures on net housing stock were published by the Government and the Post has cross-referenced them with population figures for each year since 2004.
Nationally, the greatest pressure on housing appears to be in London and the south. In Barking and Dagenham, there are 7.6 extra people for every one extra property.
In Redbridge, the figure is 6.9, in Luton 6.7 and in Kingston-upon-Thames 6.3.
At the other end of the scale, Barrow-in-Furness has seen its population fall by 3,197 over the decade while 570 extra dwellings have become available.
