>>1041My point is, you're looking for a general pattern when there isn't one. The numbers are too small.
Some people find their partner on dating sites, some bump into them while out shopping, some meet at dinner parties, some are seduced online and run off to Iraq. If, for example, there was a massive upsurge in the percentage of marriages that started at a particular market, this would be indicative of a general trend revolving around that market. But a tiny smattering is simply to be expected from random individual whims and impulses, just as any bizarre meeting scenario you could think of probably happens a few times a year. You're trying to find a picture in background noise.
