How is natural change expressed?

• A. As a ratio
• B. As a percentage
• C. In decimal form
• D. As a fraction

Answer: (B)

Natural change refers to the difference between the number of births and the number of deaths in a given population over a specific period. This change can be expressed as a percentage to provide a clear understanding of the growth or decline rate in relation to the size of the population. By transforming the natural change into a percentage, it becomes easier to compare this change across different populations or timeframes, making it a more meaningful and accessible measure.

Using a percentage also allows for a straightforward interpretation of the data, indicating what portion of the population is growing or shrinking due to natural processes, rather than other factors such as migration. This method is commonly used in demographic studies and reports, making it the standard approach for expressing natural change.
