Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. DINKY is occasionally used (in the United States, UK, Canada, India, and China) to describe a high-earning couple who do not to have children yet and are therefore able to afford a more expensive consumer lifestyle than those with families. The term was coined during the 1980s, at the height of "yuppie" culture. The post-2000 economic crises have made this social pattern more permanent as more couples wait longer than ever to have kids, and more people choose not to have them at all (1 in 5).
