ICSE Class 10 Biology Chapter 12 - Population Revision Notes

Knowledge of population demographics helps us to find out how to best provide services for the many different types of people living in that area.

Demographics are important because they show what type of people live in an area and what their needs are. Developing a plan for public services based on demographics can help save money by providing programs specifically aimed at specific populations which will be more effective than offering services to everyone.

The population chapter has many terms that might be new to you. And while reading the chapter you will certainly miss out on some of the important ones. So in the revision notes you can easily find concise and easy-to-understand definitions to these complex terms. This way even if you did not pay much attention to terms while reading, revision notes will highlight them for you. Also, the Population chapter has some numerical questions. The formulas you require to solve them are noted well for your reference in the Revision notes.

Basic terms discussed in this chapter are:

• Population density.

• Growth rate of population.

• Population growth.

• Demography.

• Population explosion.

• Natality and mortality.

• Vital index.

By understanding these terms it would be easier to know the trends that occur in the population. The consequences and causes that occur due to increase or decrease in the population. How to control it in case of increase in population and many more that are discussed in the chapter.
