Marriage statistics -- food for thought, hunger for data

I would like to know more about this: are more people getting married, or are just more couples getting registered? And is it really the case that more of a third of the registered marriages are between Georgians and foreign citizens? We should get comparative data from Armenia (which would include diaspora-marriages) and Azerbaijan. Data, data, data....
-------------------------------
"During January-September 2006, the State Registry issued marriage certificates to 4004 Georgian citizens marrying foreigners. Of those, 3611 citizens were sent documents to register their marriage from abroad and 393 Georgians married a foreigner in Georgia. Georgians marry foreigners primarily from Russia, Greece, the US, Israel, Turkey and Germany, reports the newspaper Akhali Versia."

Total registered weddings:
2005 -- 18,012
2004 -- 14,866
2000 -- 12,870
