Introduction [0:00]
The chapter primarily discusses population distribution across different areas, the reasons behind population growth, the characteristics and impacts of population, and the policies implemented to control population. Key terms such as "disaster" and "census" are introduced to provide a foundational understanding of population studies.
Disaster and Census [0:24]
A disaster is defined as a large-scale harm to the population due to natural calamities like earthquakes or tsunamis, leading to loss of life and destruction of property. A census is a survey conducted every 10 years to collect data on population characteristics such as age, education, employment, and living conditions. The first census in India was conducted in 1872, with the first complete census in 1881.
Population Distribution and Density [1:04]
In 2011, India's population was approximately 1.21 billion, which was 17.5% of the world's population. This population is unevenly distributed, with states like Uttar Pradesh, Maharashtra, Bihar, West Bengal, and Andhra Pradesh accounting for half of India's population. Uttar Pradesh alone had about 20 crore people, which is 16% of India's population. Rajasthan, despite being the largest state, holds only 5.5% of India's population. Population density measures the number of people per unit area and is calculated using the formula: Population Density = Total Population / Total Area.
Factors Influencing Uneven Population Distribution [2:29]
Population is unevenly distributed in India due to several factors. Areas with fertile land and access to water tend to have higher population densities. Developed areas offer more employment opportunities, leading to urbanization as people migrate from rural areas. Better education and healthcare facilities in developed areas also contribute to urbanization.
Population Growth and Change [3:09]
Population growth refers to the change in the number of people in a country over a specific period. It is measured in absolute numbers and percentage change per year. Absolute number shows the increase in population over a decade, while percentage change per year indicates the annual growth rate. India's population grew significantly from 36.1 crore in 1951 to 121 crore in 2011. The processes of population change include birth rate, death rate, and migration.
Birth Rate, Death Rate, and Migration [4:29]
Birth rate is the number of live births per 1000 people in a year. Death rate is the number of deaths per 1000 people in a year. India has a higher birth rate compared to its death rate. Migration is the movement of people from one place to another, categorized as internal (within the country) and international (between countries). Internal migration contributes to uneven population distribution and urbanization, as people move from rural to urban areas seeking better facilities.
Adolescent Population [5:39]
The adolescent population, aged 10-19 years, constitutes one-fifth of India's population and is a crucial resource for the future. Adolescents require more nutrition compared to children and adults. However, many adolescent girls in India suffer from anemia due to poor nutrition.
National Population Policies [6:23]
In 1952, the Indian government launched the Family Planning Program to promote responsible parenthood. In 2000, the National Population Policy focused on healthcare for children through vaccination, compulsory education up to 14 years, promoting delayed marriage for girls, and reducing infant mortality rates.
