The Full Form of HKID is Hong Kong identity.

Hongkongers (Chinese: 香港人), also known as Hong Kongese, Hongkongese, Hong Kong citizen and Hong Kong people, typically refers to legal residents of the city of Hong Kong. The word Hongkongers was officially included in the Oxford English Dictionary in 2014.

The majority of Hongkongers are of Cantonese Han Chinese descent, most of whom trace their ancestral home to the province of Guangdong. However, the city also holds other Han Chinese subgroups including the Hakka, Hoklo, and Taiwanese. Meanwhile, non-Han Chinese Hongkongers such as the British, Filipinos, Indonesians, Japanese, Koreans, South Asians and Vietnamese also make up six per cent of Hong Kong’s population.

Mainland China holds the largest number of Hong Kong expatriates, although the Hong Kong diaspora can also be found in several English-speaking countries. Most Hongkongers living outside China form a part of the larger overseas Chinese community. The migration of Hongkongers to other parts of the world accelerated in the years prior to the handover of Hong Kong from the United Kingdom to China in 1997. A second wave of Hongkongers emigrating from the city also occurred during the 2010s, as a result of the Hong Kong–Mainland China conflict.
