Understanding Population for National 5 Geography

Population Distribution and Demographic Patterns

Ever wondered why cities spring up in certain spots whilst other areas remain virtually empty? Population distribution isn't random - it follows clear patterns based on what makes life easier and more prosperous.

Physical factors like fertile soil, reliable water sources, and moderate climates naturally draw people in. Rivers provide water and transport, coastal areas offer trade opportunities, and flat land makes building easier. Mountains and deserts? Not so popular for obvious reasons.

Human factors matter just as much today. Good transport links, job opportunities, and tourist attractions create population magnets. Think about how motorways and airports transform sleepy towns into bustling centres.

Key Point: The most densely populated places combine natural advantages (like rivers) with human developments (like transport links).

LEDC vs MEDC Population Patterns

Countries at different development stages show completely opposite birth and death rate patterns. LEDCs like Kenya and Tanzania face high death rates due to disease outbreaks, limited healthcare, and poor sanitation systems.

Birth rates in LEDCs stay extremely high - often 10+ children per family. Parents need children for labour, contraception remains expensive and inaccessible, and high infant mortality means having more babies increases survival chances. Cultural attitudes towards family planning also play a role.

MEDCs like the UK show the reverse pattern. Better healthcare, reliable food supplies, and clean water keep death rates low and life expectancy high. Birth rates drop as women pursue careers, family planning becomes normal, and people delay having children.

The contrast is stark: developing countries struggle with too many births, whilst developed nations worry about not having enough babies to support ageing populations.

Key Point: A country's development level directly predicts its birth and death rate patterns.
