Population changes in terms of birth and death rate.

# data[].attributes.body
The major reason for population changes, in an individual country, is the change in birth and death rates.
-birth rate is the number of live babies born in one year for every 1000 people .
-Death rates are number of people dying per 1000 people.
When birth rates increase to a point when they are more death rates: the population logically will increase.

Climate
Preferance to comfortable climates ( rainfall and no temperature extremes.)

Acsses to fresh water.

cold temperatures make it difficult to grow crops or build homes and transport links as the ground can be frozen.

Very high temperatures make farming difficult - (dehydration/ heat stroke)

high humidity- spred of deseases like malaria.

Steep slopes make the use of machinery difficult as well as the building of houses, roads and railways.

Flat, low-lying areas have deeper soil which makes it easier to grow crops

Natural resourses like oil in an area means there is a sourse of industry and therefore a sourse of employment opportunities.

Scenery is a resource and can attract tourists, bringing job opportunities.

Children are expected to look after parents because of a lack of pensions.

Lack of knowledge in contraception and family planning.

High infant mortality rates, so perants have more children.

Death rates are higher:

Food insuqurity

Poor sanitation and lack of clean drinking water.

Natural disasters destroying crops.

High levels of disease, eg malaria.

Lack of doctors, medicines and healthcare.

War

# data[].attributes.body
Low birth rates

Women's status has improved.

Contraception

Careers are more important than having a family.

The cost a baby has increased.

Marrage later in life

Increased desire for material possessions, eg cars and holidays instead of children

A developed country with low population density and a low percentage of employable people may have higher demand for workers, thus an increase in wages, and more resourses for each individual.

Over population and limited resourses (enviroment and public)

# data[].attributes.body
With an increase in the number of people living in a particular area. Since population grows exponentually; resource depletion can occur rapidly, leading to specific environmental concerns such as global warming, deforestation, and decreasing biodiversity.

With limited resourses (natrual, healthcare, eductation) for an increasing number of people, prices may increase and gentral standards of living may decrease.

A higher population may keep the economy developing, thus gving indervidules more economic opertunities for employment and genral higher standards of living due to subsidisation causes by compatition. However, on the other hand, a high population with minimal economy may have employment issues and low wages.
