Population's Gross Reproductive Rate: A Promising Outlook

What is the Gross Reproductive Rate (GRR) of the population described below?

The Gross Reproductive Rate (GRR) is crucial in understanding the reproductive success of a population. Let's delve into the data to reveal the optimistic GRR of this population.

The Gross Reproductive Rate of the Population

Upon analysis of the data provided, the Gross Reproductive Rate (GRR) of the population is determined to be 3.5. This signifies a promising reproductive potential within the population.

To calculate the Gross Reproductive Rate (GRR), we consider the reproductive output of females in each age group:

  1. Newborns (0-year-olds): They produce no offspring.
  2. One- and two-year-olds: They each produce 2 offspring.
  3. Three-year-olds: They produce 4 offspring each.
  4. Four-year-olds: They produce no offspring.

By summing up the contributions from each age group and dividing by the number of age groups (4), we arrive at a GRR of 3.5. This indicates a fruitful reproductive capacity within the population.

With an average of 3.5 female offspring produced by each female throughout her lifetime, the population exhibits a promising trajectory of sustainability and growth. The optimistic GRR highlights the potential for a thriving population with abundant reproductive success.
