Men tend to be older than women in a relationship
Yep in 67% of relationships the male is older, in 20% the female is older and 13% of couples are the same age. On average the male is 2.4 years older. Australia has the closest age parity with an average gap of only 1.8 years.
Religion does play a part. It seems that people are willing to date people with a different religion but are less likely to marry them. In Australia around 77% of relationships are with people of the same religion.
Will we still be together?
The most important aspect is time. The longer you have stayed together the less likely to split up. Most relationships end in only a few months. As the chart below shows if you can make it past 6 months your % chance of staying together dramatically increases.
How couples interact on FB
Before a relationship starts there is a slow and steady increase in messaging. However as the relationship begins there is less messaging as couples spend more time together in the real world. Less FB can sometimes be a good thing! While users post less in a relationship FB found that they express more positive messages to each other.
No information for Australia but the best places to look if you're an Australian in the US is by going to the towns with the highest % of most single people
You can always count on your friends
Things do not always work out as planned and if your relationship does go south you can count on your friends. Your support network on FB does seem to work with the amount of interactions increasing when a relationship status is updated on FB. As can be seen below messages increase by 225% on the day of the update versus the average volume of interactions the prior weeks.
