In 2023, the total population of the Guangdong - Hong Kong - Macao Greater Bay Area in Greater China ranged at ***** million. The Guangdong - Hong Kong - Macao Greater Bay Area is the largest and most populated urban area in the world.

This statistic illustrates the population of the Guangdong - Hong Kong - Macao Greater Bay Area cities in 2023. That year, the population of Guangzhou amounted to approximately 18.83 million people, making it the largest city by population in the region.

In 2022, the total population of the Guangdong - Hong Kong - Macao Greater Bay Area reached around 86.6 million. In terms of population, China's Greater Bay Area was larger than other major Bay Areas in the world. However, per capita GDP was only about half of that in the Tokyo Bay Area and only one seventh of that in the San Francisco Bay Area.

The data and codes that used in the research "Spatial Cooperative Simulation of Land Use-Population-Economy in the Guangdong-Hong Kong-Macao Greater Bay Area, China" was attahced as follows.The PLUS model was used as one kind of basic simulation models in this study. The software can be found in the "./plus_model" folder. A README file was included in this folder to show how the software can be utilized to implement our approach.The original data of land use, population, and economy can be found in the './original_data' folder and the corresponding driving factor data can be found in the './driving_factor' forlder. All these files was resampled into 1 km grids. These files were used as input data for simulation.The simulation results were included in the './simulated_data' folder. It included the simulation results of land use, population, and economic productions with our proposed approach. With the codes in the './ca_code' folder and the files in the './code_file' folder, the performance of our proposed approach can be evaluated with baseline approaches.The predicted scenarios of land use, population, and economic productions in the year of 2030 were included in the './predicted_data' folder.

In 2023, the total land area of the Guangdong - Hong Kong - Macao Greater Bay Area cities amounted to around ****** square kilometers. The land area of Zhaoqing alone was nearly ****** square kilometers, making it the largest city by area in the region. In terms of population size, however, Zhaoqing is one of the smaller cities in the Greater Bay Area.

By 2035, nearly ** million people are predicted to call Guangzhou home. As one of the key cities in the Guangdong-Hong Kong-Macao Greater Bay Area, Guangzhou’s vibrancy is very attractive to people searching for their opportunities there.

Megacity – Guangzhou

As China’s cities become increasingly urbanized, the demographic of this megacity has also changed considerably over the years, with more and more Chinese locals and foreigners opting to dwell in Guangzhou for work and cultural opportunities. Together with Beijing, Shanghai and Shenzhen, Guangzhou is listed as one of China’s first-tier cities, indicating its great economic power and developing potential. Guangzhou has been a large port of China for over *** thousand years and has contributed significantly to the economic and cultural exchange between China and the world. Today, the Guangzhou Port is one of the largest in the world.

Multicultural hub

The traces of immigrants from different times to this city can be easily found in Guangzhou’s architecture. In the former colonial area, there are still plenty of old western style buildings. Today’s Guangzhou is one of the Chinese cities with the highest density of skyscrapers in some business areas. The Canton Tower, landmark of Guangzhou, is *** meters tall and the second tallest tower in the world after Tokyo Skytree. In this capital city of the Guangdong province, Cantonese culture is highly respected and well developed. Guangzhou is also one of the Chinese cities with the largest foreign population. Cantonese, Mandarin and English are the widely used languages of the residents in Guangzhou.

The data for this study are drawn from the data collected for a larger project entitled “A Systematic Study of Labour Dynamics in the Greater Bay Area” funded by Our Hong Kong Foundation.

This specific data set looks at the labour migration of highly educated Mainland Chinese in Hong Kong with the data collected between fall of 2019 to spring of 2020 with 3,012 respondents. My research draws from this data set and examine the social integration of these migrants, in particular i) whether discrimination at work and in daily life has different influences in their friendship making patterns with locals and ii) the impact of mental health on staying intention when they perceive discrimination. This data set serves as a foundation to understanding the highly educated Mainland Chinese migrant population in Hong Kong and enriches our understanding of highly educated migration within Asia.

Stata 14.0 was used to analyse the data.

Shenzhen is one of the fastest growing cities in China. Based on estimates, the population of Shenzhen is expected to reach over ** million by 2035. This rapidly growing city is attracting an increasing number of young Chinese, who want to start and grow their careers.

Development history of Shenzhen 

Shenzhen is located next to Hong Kong, one of the key financial and business centers of the world.  The city has a short history - Shenzhen wasn’t technically a city until 1979. Now, it is home to the largest economy in China’s Greater Bay Area, surpassing its neighbor Hong Kong. Shenzhen is also called China’s Silicon Valley, since many China’s tech-giants are headquartered there. As a rising financial center, Shenzhen also hosts one of the two Stock Exchanges in Mainland China. The headquarter of China’s leading insurance company Ping An Insurance is in Shenzhen as well.

Immigration to Shenzhen 

Enticed by its fast-developing economy, people from across the whole country have relocated to Shenzhen to take their chances at new job and life opportunities. In its 40-year development, countless migrant workers have contributed to this city’s construction projects and labor-intensive manufacturing production. Many young graduates have found it easier to find a job in Shenzhen compared to other first-tier cities. Promotion opportunities have attracted top talent in many sectors to come to this city. Accordingly, with the rise of population, the cost of housing in Shenzhen has also seen a drastic increase.

By the end of 2023, around 11.39 million people were employed in Guangdong's capital Guangzhou. As a part of China's Guangdong-Hong Kong-Macau Greater Bay Area, Guangzhou has attracted various Chinese and foreigners to work in the city.
