Hopes & Fears examined how common divorce is, and how long the average marriage lasts in some of the world's major cities, including New York:
1. Rome, Italy: 15 to 18 years
Separation and divorce rates have been rising at 30.7 percent since 2010 in Rome, according to Istat. Every 1,000 marriages have an equivalent of 307 separations and 182 divorces as of 2010.
However, Rome still has the most couples who stay together long term, at 15 to 18 years, including the years of separation until the time of divorce, according to The Economist.
2. Ottawa, Canada: 13.8 years
The average length of a marriage in Ottawa is 13.8 years, according to Statistics Canada. However, with divorce rates continuously rising with the national divorce rate at 48 percent, Hopes & Fears says this number may have changed.
3. Paris, France: 13 years
Surprisingly, even the city of love isn't immune to failing marriages, with the divorce rate at 55 percent. The average length of a marriage is 13 years, according to Eurostat.
4. New York City, USA: 12.2 years

5. Mexico City, Mexico: 12 years
According to Reuters, the average marriage in Mexico lasts around 12 years. Divorce is only at 15 percent, but recent studies show that many couples have been breaking up after only 2 years of marriage.
