Look at the numbers again:
Year ... Marriages
2014... 2,140,272
2013... 2,081,301
2012... 2,131,000
2011 ... 2,118,000
2010... 2,096,000
2009... 2,080,000

The number of weddings change each year, but the remarkable thing isn't that they rise or fall from year to year. The remarkable thing is how constant the number is. The variance is tiny from year to year.

When the number of weddings in a year drops below a million in a given year you might have a case. But, at a rate of 2 Million new married couples each year, your case fails hard. Very Hard. Total Fail.
