"Population" refers to the total number of individuals or organisms of a particular species living in a specific area or environment at a given time.  POPULATION SIZE IN INDIA On March 2001, India’s population was 1,028 million which is about 16.7% of the world population. Uttar Pradesh, with a population of 166 million, is the most populous state of India. The state accounts for 16% of the total population of the country. Sikkim has a population of about 0.5 million people, and Lakshadweep has only 60,000 people. WHAT IS POPULATION DISTRIBUTION? Population distribution describes how people are located across different areas. It tells us which places have more people living close together (like cities) and which places have fewer people spread out (like countryside or remote areas). It helps us understand where people choose to live and why some areas are more populated than others. POPULATION DISTRIBUTION IN INDIA Nearly half of the population of India lives in five states— Uttar Pradesh, Maharashtra, Bihar, West Bengal and Andhra Pradesh. Rajasthan, the largest state in India, has only 5.5% of the total population of the country.  POPULATION DENSITY Population density is a measure of how many people live in a specific area, usually per square kilometer or mile. It tells us if a place is crowded or sparsely populated. For example, if many people live in a small area, the population density is high (like in a city). If fewer people are spread out over a large area, the population density is low (like in rural areas). Distribution is about location (where people are). Density is about numbers (how many people are in one spot). Short Answer Questions (2 Marks Each) 1. Define the term "growth of population." 2. How is the absolute number of population growth calculated? 3. What is the significance of a declining growth rate for a country like India? Long Answer Questions (5 Marks Each) 1. Discuss the two ways in which the change in population can be expressed, as mentioned in the passage. 2. Analyze how the population growth in India from 1951 to 2001 reflects the country’s demographic trends. Data-Based Question (3 Marks) 1. India’s population grew from 361 million in 1951 to 1,028 million in 2001. Calculate the absolute growth in population during this period. 1.Define the term "growth of population." ◦ Refers to the change in population at a specific time. ◦ Expressed in absolute numbers or percentage. 2.How is the absolute number of population growth calculated? ◦ Subtract the earlier population from the later population. 3.What is the significance of a declining growth rate for a country like India? ◦ Indicates success in birth control measures. ◦ Reflects progress towards population stabilization. Long Answer Questions (5 Marks Each) 1.Two ways to express population change: ◦ Absolute Numbers: Total increase, calculated by subtracting the earlier population from the later one. ◦ Percentage/Growth Rate: Annual growth rate expressed as a percentage, useful for analyzing trends. 2.Population growth in India (1951–2001): ◦ Grew from 361 million to 1,028 million, indicating steady growth. ◦ Early decades: Reflects improved healthcare and high birth rates. ◦ Later decades: Declining growth rate shows successful family planning and awareness. ◦ Indicates India’s shift towards demographic stabilization. DBQ: (Answer: 1,028 million - 361 million = 667 million) PROCESS OF POPULATION CHANGE Birth rate Death rate Migration AGE COMPOSITION 15- 59 60< 0-14
