step 1 Hello there's students. So today we're going to figure out what is the net reproductive rate. An

Refer to the following table: Age nx dx lx ...

Refer to the following table: $$ \begin{array}{llllll} \text { Age } & n_{x} & d_{x} & l_{x} & m_{x} & l_{x} m_{x} \\ 0 & 100 & 35 & 1.00 & 0 & 0 \\ 1 & 65 & ? & 0.65 & 0 & 0 \\ 2 & 45 & 15 & ? & 3 & 1.35 \\ 3 & 30 & 20 & 0.30 & 1 & ? \\ 4 & 10 & 10 & 0.10 & 1 & 0.10 \\ 5 & 0 & 0 & 0.00 & 1 & 0.0 \end{array} $$ What is the net reproductive rate? a. 5 b. 2.5 c. 1.75 d. 1.45 e. 0.80

Key Concepts

Life Table

A life table is a demographic tool that summarizes the survival and reproductive rates of a population across different age groups. It includes variables such as survivorship (l_x), the number of individuals surviving to a given age; mortality (d_x), the number of individuals dying during the age interval; and fertility (m_x), the average number of offspring produced by individuals of a specific age.

Net Reproductive Rate (R0)

The net reproductive rate, often denoted as R0, is the average number of offspring that an individual is expected to produce over its lifetime. It is calculated by summing the products of the age-specific survivorship (l_x) and fertility (m_x) across all age classes where reproduction occurs, providing a key indicator of population replacement levels and long-term growth potential.

Age-Specific Fertility and Survivorship

Age-specific fertility rates (m_x) and survivorship (l_x) are critical components of a life table. They provide a detailed view of the reproductive output and survival probability of individuals at each age, which together are used to evaluate the overall reproductive contribution of the population through calculation of metrics such as the net reproductive rate (R0).
