Summary

This educational video provides an in-depth guide on how to calculate population growth, focusing on three key types: natural growth (births and deaths), non-natural growth (migration), and total population growth. The video explains the relevant formulas for each type and provides detailed examples to demonstrate the calculations. The presenter also categorizes growth rates into low, medium, and high, helping viewers understand where a particular city’s growth falls within these categories. It is an informative resource for understanding the dynamics of population and how to compute them using specific formulas and real-life examples.

Takeaways

• 😀 Understanding population growth involves calculating the difference between birth and death rates in a specific area over a given period.
• 😀 The formula for calculating natural population growth is: P = L - M, where P is the growth, L is births, and M is deaths.
• 😀 To calculate the percentage growth rate, the formula is: (L - M) / Po * 100, where Po is the initial population.
• 😀 An example was given with the city of X in 2023, where there were 4,280 births, 240 deaths, and an initial population of 200,000.
• 😀 The result of the population growth calculation for city X in 2023 was an increase of 2,240 people.
• 😀 To calculate the natural population growth rate percentage, the result was 1.12%, which falls into the 'moderate' growth category (1-2%).
• 😀 Population growth can be classified into three categories: low (below 1%), moderate (1-2%), and high (above 2%).
• 😀 Non-natural population growth, or migration, is calculated similarly: PM = (I - E) / Po * 100, where I is immigration and E is emigration.
• 😀 The migration growth rate example in city X showed a 0.17% growth rate, which is classified as 'low'.
• 😀 Total population growth combines both natural and non-natural growth, using the formula: PT = (L - M + I - E) / Po * 100.
• 😀 The total population growth in city X was calculated to be 1.29%, which falls into the 'moderate' category for growth rate.
• 😀 Further learning resources, including videos on how to calculate natality, mortality, migration, and population projections, are available for deeper understanding.

Q & A

What is the formula for calculating natural population growth?

The formula for natural population growth is P = L - M, where P is the natural population growth, L is the number of births, and M is the number of deaths in a given region.

How do you calculate the percentage of natural population growth?

To calculate the percentage of natural population growth, use the formula: Percent P = ((L - M) / Po) * 100, where L is the number of births, M is the number of deaths, Po is the population at the start of the year, and the result is the percentage growth.

In the example for city X, how was the natural population growth calculated for the year 2023?

For city X in 2023, the natural population growth was calculated as P = 4,280 (births) - 2,040 (deaths) = 2,240 people.

What does a 1.12% natural population growth rate mean for city X?

A 1.12% natural population growth rate means that the population in city X increased by 1.12% in 2023, which is categorized as 'medium' growth based on the criteria provided in the script.

How do you calculate non-natural (migration) population growth?

Non-natural (migration) population growth is calculated using the formula: Percent PM = ((I - E) / Po) * 100, where I is the number of immigrants, E is the number of emigrants, and Po is the population at the start of the year.

In the example for city X, how was the migration population growth calculated for 2023?

For city X in 2023, the migration population growth was calculated as PM = 970 (immigrants) - 630 (emigrants) = 340 people. The migration growth rate was then calculated as 0.17%.

What does a 0.17% migration growth rate indicate about city X?

A 0.17% migration growth rate indicates that the migration in city X in 2023 was very slow or low, which is categorized as 'low' growth.

What is the formula for calculating total population growth?

The formula for calculating total population growth is: P or PT = (L - M) + (I - E), where L is the number of births, M is the number of deaths, I is the number of immigrants, E is the number of emigrants.

How was the total population growth for city X calculated in 2023?

For city X in 2023, the total population growth was calculated as PT = (4,280 - 2,040) + (970 - 630) = 2,240 + 340 = 2,580 people. The total growth rate was 1.29%.

What does a 1.29% total population growth rate mean for city X?

A 1.29% total population growth rate means that the overall population of city X increased by 1.29% in 2023, which falls within the 'medium' growth category.
