Singapore's land area is so small that Singaporeans are more likely to go abroad. Especially, I saw a lot of cars moving between Malaysia and Singapore. This can be thought as a reason why many Singaporeans go abroad. But, the following trend is similar to that in Japan
"Most are between 20 and 54 years old, with slightly more women than men"
※Cited from the article
The number of Japanese men passports issued is less than that of Japanese women passports. In Asian countries' spots, I often see Japanese ladies tourists. It may be because more and more ladies become active.
I wonder why it is also true for Singaporeans.
