Bao'an District () is one of the nine districts comprising the city of Shenzhen, Guangdong province. It is one of the districts formerly lying outside the Shenzhen Special Economic Zone. History Bao'an was the historical name of Bao'an County (also known as Xin'an County) of the Qing dynasty, which included area of modern-day Shenzhen and Hong Kong. The area of today Bao'an District, was integrated into Shenzhen in 1979, which the Bao'an County was promoted as a city. Bao'an was reverted into county status in 1981, as the administrative unit of the area that belongs to Shenzhen, but now belongs to Shenzhen Special Economic Zone. Border patrols were also established in the border of the Economic Zone. In 1991, Shenzhen Bao'an International Airport, located in Bao'an County, was opened. Finally Bao'an district was established on January 1, 1993. Two New Districts () were created as sub-districts of Bao'an district, namely Guangming and Longhua new districts, in 2007 and 2011 respectively. In 2010, Shenzhen Special Economic Zone was enlarged to cover the whole Shenzhen city. Rapid development occurred in the Bao'an District. Longhua District was separated from Bao'an and became a district on 11 October 2016. In 2018, Guangming District was also separated from Bao'an District. Demographics The district had a population of 4,476,554 by November, 2020. About 85% of Bao'an's population are migrants from other parts of China, most speaking Standard Chinese (Standard Mandarin). Hence this made Standard Chinese the primary Chinese variety spoken in the district. Cantonese is also widely spoken, between locals and migrants from around Guangdong Province (Canton Province). Public Safety Bao'an has, as of 2008, a notoriously bad safety record. Since the turn of the millennium, the district has seen a string of high-profile abductions, robberies, and other cases of violent crime. However, in the last four years, this has become less of an issue with an increased police presence and higher average income in the district.
