There are typically marked spikes in the birth rates of countries that use the Chinese zodiac or places with substantial Chinese populations during the Year of the Dragon, because these births are considered to be lucky and have desirable characteristics that supposedly lead to better life outcomes.[8][9] The relatively recent phenomenon of planning a child's birth in a Year of the Dragon has led to hospital capacity issues and even an uptick in infant mortality rates toward the end of these years due to strained neonatal resources.[citation needed]
