Population worksheet with true/false questions and three population pyramid graphs for analysis.

Let's solve the problem step by step.

---

1. Write true or false. Correct the false sentences.

#### a) Population density tells us how many children each family has.
- False
- Correction: Population density tells us how many people live in a given area (usually per square kilometer or mile). It does not tell us how many children each family has.

#### b) People who study population are called demographers.
- True

#### c) The largest gender group in Spain is Catholic.
- False
- Correction: Gender groups are male and female. "Catholic" is a religion, not a gender. So this sentence is incorrect because it mixes up categories.
- Corrected sentence: The largest religious group in Spain is Catholic.

#### d) Migration is the movement of people from one area or country to another.
- True

#### e) Population density is higher in cities than in rural areas.
- True

#### f) Pyramid charts usually give us information about ethnic groups.
- False
- Correction: Pyramid charts (age-sex pyramids) show the distribution of a population by age and gender. They do not typically provide information about ethnic groups.
- Corrected sentence: Pyramid charts usually give us information about age and gender distribution.

2. Look at the pyramid graphs. Answer the questions.

We have three population pyramids: a), b), and c).

Let’s analyze them:

- Graph a): Wide base (many young people), narrow top → young population → growing population.
- Graph b): Narrow base, wider middle and top → older population → decreasing or stable population with low birth rates.
- Graph c): Broad middle, narrow base → fewer children, larger working-age population → likely a population that has been declining for years.

Now answer the questions:

#### a) Which graph shows a population that has been decreasing for many years?
- Answer: Graph c)
- Explanation: The base (youngest age groups) is narrow, indicating low birth rates over time. The population bulges in the middle, suggesting past high fertility but now aging. This shape is typical of countries with long-term population decline.

#### b) Which graph shows a population that is increasing?
- Answer: Graph a)
- Explanation: The wide base indicates many young people, which suggests high birth rates and a growing population.

#### c) Which graph has the lowest number of children aged 0–9?
- Answer: Graph b)
- Explanation: The bars for the 0–9 age group are the shortest in graph b), meaning fewer children.

#### d) Which graph has the highest number of children aged 0–9?
- Answer: Graph a)
- Explanation: The 0–9 age group has the widest bars in graph a), indicating the most children.

#### e) Which graph do you think is similar to the population of Spain? Why?
- Answer: Graph b)
- Explanation: Spain has a low birth rate, an aging population, and a shrinking younger generation. The population pyramid of Spain is often characterized by a narrow base and a broader middle/older section — exactly like graph b). This reflects low fertility and an aging society, common in developed European countries.

✔ Final Answers Summary

#### 1. True or False
a) False → Population density measures people per area, not family size.
b) True
c) False → "Catholic" is a religion, not a gender; corrected: The largest religious group in Spain is Catholic.
d) True
e) True
f) False → Pyramid charts show age and gender, not ethnicity.

#### 2. Pyramid Graphs
a) Graph c) – decreasing population
b) Graph a) – increasing population
c) Graph b) – lowest number of children (0–9)
d) Graph a) – highest number of children (0–9)
e) Graph b) – similar to Spain due to low birth rates and aging population.
