Processes of Population Change/Growth

Population change is vital to understand for any society, particularly in a vast and diverse country like India. There are three main processes of population change: birth rates, death rates, and migration.

Key Point 1: Natural Increase of Population

The natural increase of population is determined by the difference between birth rates and death rates.

• Birth Rate:

  • This refers to the number of live births per thousand individuals per year.
  • It is an important factor in population growth.
  • In India, birth rates have traditionally been higher than death rates.

  Examples:

  1. If a country has a birth rate of 25 per 1000, this indicates a relatively high population growth potential.
  2. Sociocultural factors like early marriages can lead to increased birth rates.

• Death Rate:

  • This refers to the number of deaths per thousand individuals per year.
  • A declining death rate can lead to growth in population even if birth rates decline.

  Examples:

  1. Advances in medical healthcare that reduce the death rates in infectious diseases.
  2. Improved living conditions that extend life expectancy lead to a lower death rate.

Growth Trend in India:

• Until 1980, the high birth rates combined with falling death rates resulted in significant population growth.
• Post-1981, birth rates began to decline, slowing growth rates, attributed to improved healthcare and family planning.

Key Point 2: Migration

Migration is the movement of people and significantly influences population change.

• Internal Migration:

  • Movement within a country affects population distribution but not overall size.

  Examples:

  1. Individuals moving from rural areas to cities for better job opportunities.
  2. Families relocating to urban centers for better education.

• International Migration:

  • Movement between countries impacts both population size and demographic composition.

  Examples:

  1. Workers migrating from India to Gulf countries for employment.
  2. Students moving abroad for higher education, affecting the home country's demographics.

Role of Migration in Population Change:

• Urbanization is driven largely by rural-to-urban migration influenced by push and pull factors.
  • Push factors include poverty, unemployment, and lack of services in rural areas.
  • Pull factors include better employment prospects and living conditions in urban areas.

Key Point 3: Adolescent Population

The adolescent population, aged 10 to 19 years, is a significant segment of India's population, constituting about one-fifth.

• Nutritional Needs:

  • Adolescents have different nutritional requirements to support rapid growth. They require a diet richer in nutrients.

  Examples:

  1. Increased need for iron to prevent anaemia, especially in girls.
  2. Additional calcium and protein for proper development during these growth spurts.

• Health Issues:

  • Poor nutrition leads to health issues such as anaemia and stunted growth.

  Examples:

  1. High prevalence of anaemia among adolescent girls due to inadequate dietary intake.
  2. Lack of awareness can lead to poor lifestyle choices affecting overall health.

• Lack of Attention:

  • Issues faced by adolescent girls regarding education and health remain under-addressed.

  Examples:

  1. Limited access to reproductive health education.
  2. Need for outreach programs to raise awareness about health and nutrition.

Key Point 4: National Population Policy

The National Population Policy (NPP) 2000 is designed to manage population growth effectively.

• Objectives of NPP (2000):

  • Free and compulsory education for children up to 14 years.
  • Set a target to reduce the infant mortality rate below 30 per 1000 live births.

  Examples:

  1. Building schools in rural areas to ensure accessible education.
  2. Campaigns for immunizing infants against diseases.

• Universal Immunization:

  • Critical for reducing mortality rates among children.

  Example:

  • Vaccination programs for diseases like polio and measles.

• Delayed Marriage Promotion:

  • Encouraging girls to marry later can impact birth rates positively.

  Examples:

  1. Education campaigns that illustrate the benefits of delaying marriage.
  2. Financial incentives for families delaying marriage for their daughters.
