Population

Bevolkingsgrafiek

Piramide                                                               Ui

Ghana: 
- Veel kinderen 

- lagere levensverwachting

- grote natuurlijke bevolkingsgroei  

Engeland:

- grote groep 40 50 ers

- hogere levensverwachting

- Ook sociale bevolkingsgroei

To read a population pyramid, focus on:

• The shape (expansive, constrictive, or stationary).
• The size of the base (indicating birth rates).
• The distribution of males and females.
• Age groups to understand the population's structure and potential future challenges or growth patterns.
• By interpreting these elements, you can understand important demographic trends and make inferences about a region's future needs, such as healthcare, education, and workforce planning.

Repetition of previous lesson

Goals: 

You can explain what population density and population distribution are.

You recognize the difference between these two concepts.

You know what sparsely populated and densely populated mean.

You can explain why certain areas are sparsely populated or densely populated

Difference between population density and population distribution

• Population density : The number of people per square kilometer on average in a given area
• Population distribution refers to how people are spread out over an area,  where people are concentrated or dispersed

Population density: 

This is the number of people per square kilometer in a given area. It indicates how densely populated an area is. You calculate this by dividing the total number of people in an area by the area’s size. For example, if a country has 10 million people and an area of 100,000 km², the population density would be 100 people per square kilometer.

Population distribution:

 This refers to how the population is spread out over a given area. It looks at where people are concentrated or dispersed. In a country with uneven population distribution, one area might be very densely populated (e.g., large cities), while another area may be almost empty (e.g., remote rural regions).

Population density is ...?

1. The average number of inhabitants
2. The average number of inhabitants per km2
3. How much population there is
4. How many people live in a house

To calculate the population density you :

1. Number of inhabitants : number of km2 of the area
2. Area km2: number of inhabitants

Calculate the population density.
Number of inhabitants 800
Surface area 4 km²

1. 3.200
2. 0,005
3. 200
4. ?

Population density

Population density

Number of inhabitants per square kilometre

Densely populated areas

    - high population density

Sparsely populated areas

    - low population density

Population density

In which part of the Netherlands is the population density the highest? N-S-W-E?

 Bevolkingsgrafiek

Wat moet je kunnen?

• Ik kan uitleggen wat een bevolkingsgrafiek is.
• Ik kan  informatie uit een bevolkingsgrafiek halen.
• Ik kan een bevolkingsgrafiek tekenen.

Bevolkingsgrafiek

Een grafiek waarin je per leeftijdsgroep het aantal mannen
en vrouwen in een land kunt
aflezen.

Klaar?

Pak de vaardighedenparagraaf Zoeken in het trefwoorden- of zaakregister (werkboek p. 35). Onder het groene kopje "Hulpvaardigheden" staat een informatietekst over bevolkingsgrafieken. Lees deze tekst door.

bevolkingsgrafiek

De bevolkingsgrafiek in arme landen heeft een piramidevorm. In rijke landen is dit een ui-vorm.
