Population distribution patterns in China

China's population is distributed unevenly across the country, with a significant concentration in the eastern regions, particularly along coastal areas and river valleys. This imbalance is largely influenced by the physical geography of the nation, where much of the western and central areas consist of deserts and mountainous terrain unsuitable for dense settlement.

Factors influencing population distribution in China

• Eastern concentration - Over 10% of China's population resides on less than 1% of the land, primarily in the east, where fertile plains and access to water support habitation. Half of the population lives on less than one-tenth of the land.
• Sparse western regions - Less than one-twentieth of the population lives on half of the land in areas like Tibet and Inner Mongolia, due to harsh environmental conditions.
• Agricultural suitability - Only a small fraction of the country supports rain-fed agriculture, mostly in the east, contributing to higher population densities.
• Trade and commerce advantages - Coastal and riverine locations in the east are ideal for economic activities, attracting more people.
• Urbanisation trends - There is a growing shift towards urban centres, with over 50 cities now housing more than a million people each, and projections of an additional 350 million urban dwellers by 2020.
• Mega-regions development - Clusters of megacities and large urban areas are forming, further concentrating populations in specific zones.

Internal migration trends in China

China has witnessed one of the largest internal migration movements globally in recent decades. Millions have relocated from rural to urban areas, driven by economic opportunities, significantly impacting both the economy and the migrants themselves.

Scale and patterns of internal migration

• Scale of movement - Approximately 160 million individuals have migrated from rural regions to urban centres seeking better employment prospects.
• Historical shifts - Between 1990 and 2005, over 80 million people moved towards coastal urban-industrial hubs, reflecting a sharp increase in migration flows over time.

Impact of internal migration

• Economic benefits - This migration has bolstered China's economy by providing a workforce for industrial growth, while many migrants benefit from higher wages.
• Personal and environmental costs - Migrants often face challenges such as separation from family and poor living conditions, alongside environmental strain in urban areas due to rapid growth.
• Government intervention - Rising land and labour costs in coastal cities have prompted the government to redirect industrial development and migration towards interior regions to balance growth.

Population distribution patterns in South Africa

South Africa's population distribution is highly uneven, with dense concentrations in economically significant areas and sparse populations in more remote regions. This pattern reflects historical, economic, and environmental factors that shape where people live.

Factors influencing population distribution in South Africa

• Core economic regions - High population densities, often exceeding 1,000 people per km², are found in areas like Gauteng province, driven by economic opportunities in cities such as Johannesburg and Pretoria.
• Peripheral sparsity - Large areas, such as the Northern Cape Province, have very low densities, often below 5 people per km², due to arid conditions and limited resources.
• Resource-rich areas - Regions with valuable minerals, like gold and diamonds near Johannesburg and Kimberley, attract significant populations.
• Agricultural potential - Areas with fertile land, such as the Garden Route, support higher densities through farming activities.
• Trade hubs - Coastal cities like Durban and Cape Town draw populations due to their roles as major trading centres.

Internal and international migration in South Africa

Migration, both within South Africa and from other African nations, plays a crucial role in shaping the country's demographic landscape. Historical policies and current economic disparities continue to influence these movements.

Internal migration patterns in South Africa

• Apartheid-era forced migration - During the apartheid period, over 4 million black South Africans were forcibly relocated to designated homelands like Transkei and KwaZulu, disrupting traditional settlement patterns.
• Post-apartheid urbanisation - Since the end of apartheid, urban population has risen from 55% in 1995 to 65% in 2015, as many moved to cities seeking employment and better living conditions.
• Economic pull factors - Large cities like Johannesburg attract internal migrants due to perceived job opportunities and improved infrastructure.

International migration to South Africa

Scale and origins of international migration:

• South Africa, often termed the "Rainbow Nation," draws between 1.5 million and 3.2 million migrants, primarily from neighbouring African countries, due to its relative economic stability and wealth.
• About two-thirds of these migrants come from within Africa, including nearby nations and as far as Morocco and Eritrea, with many settling in areas like Mayfair in Johannesburg.

Continental displacement context:

• Of the 17 million displaced Africans globally, most remain on the continent, with only about 3% heading to Europe; South Africa is a key destination.
• New and ongoing conflicts in countries such as Burundi, Libya, Niger, Nigeria, Central African Republic, Democratic Republic of the Congo, and South Sudan have increased displaced populations by around 20% in recent years.

Challenges facing migrants:

• Migrants often face hostility, with periodic violence driven by competition for scarce jobs, housing, and services.
• South Africa holds the highest number of pending asylum claims worldwide, with over a million applications awaiting processing, indicating sustained migration pressures.
