FAQs on Population: Birth & death Rate, Sex Ratio Video Lecture - NEET
| 1. What is the birth rate and death rate in population dynamics? |  |
Ans. The birth rate in population dynamics refers to the number of births that occur in a specific population over a specific period of time, usually expressed as the number of births per 1,000 individuals. On the other hand, the death rate refers to the number of deaths that occur in a specific population over a specific period of time, usually expressed as the number of deaths per 1,000 individuals.
| 2. How is the sex ratio calculated in population studies? | |
Ans. The sex ratio in population studies is calculated by dividing the number of males in a population by the number of females, and multiplying the result by 100. This ratio provides an indication of the proportion of males to females in a given population.
| 3. What is NEET and how is it related to population dynamics? | |
Ans. NEET stands for Not in Education, Employment, or Training. It is a term used to describe individuals who are not currently engaged in any form of education, employment, or training. NEET is related to population dynamics as it provides insights into the proportion of young individuals who are not actively contributing to the workforce or pursuing further education, which can have implications for a country's economic growth and social development.
| 4. How can birth and death rates impact population growth? | |
Ans. Birth and death rates play a significant role in determining population growth. When the birth rate is higher than the death rate, the population tends to experience growth. Conversely, when the death rate exceeds the birth rate, the population may decline. Understanding and managing birth and death rates is crucial for effective population planning and resource allocation.
| 5. What are some factors that can influence birth and death rates in a population? | |
Ans. Several factors can influence birth and death rates in a population. These factors include access to healthcare, socio-economic conditions, education, cultural norms, government policies, and contraceptive use. Improvements in healthcare and living conditions, as well as the availability of family planning services, can contribute to lower birth and death rates, while adverse conditions may lead to higher rates.
