The small number of newborn babies, which has been caused by high prices and the changing social situation of women, is one of the most serious problems in Asia. When people talk about it, you can hear a word invented in Japan. which means Double Income Kids(小孩).

In many major Asian cities like Seoul, Singapore, and Tokyo, the cost of a ****** is extremely high. A young couple who want to buy their own house may have to pay about $3000,000 (though prices have fallen). For a flat with one bedrooms, one dining-room, a kitchen, and a bathroom, the couple will pay about $900 a month. What’s more, if they want to have a child, the child’s education is very expensive.
