New figures released by the Office for National Statistics reveal the number of opposite-sex marriages decreased by 3.4 per cent between 2014 and 2015, to 239,020.
Harry Benson, a Christian at the Marriage Foundation, a group which promotes marriage as a source of family stability, told Premier: "It's pretty dire.
"If you have less marriage, it means less commitment and it means more family breakdowns.
"We, in Britain, languish at the bottom of a rather shameful league table for family stability amongst the whole of the developed world.
The number of opposite-sex couples choosing to get married has now reached its lowest level since records began in the 1830s or 1840s.
Coalition for Marriage, a group which supports the traditional common-law definition of marriage, said the figures were regrettable and highlighted a need for the Government to better-support marriage via education and the tax system.
Campaign director, Thomas Pascoe, a Christian said: "It is a matter of great regret that the number of marriages continues to fall, exactly as we feared.
"Unless the Government is prepared to put actions in place of warm words on marriage, we will see this great engine of social mobility become purely the reserve of the better-off."
