Which of the following is NOT a major population estimation method?

1. Linear Method

2. Ratio Method

3. Statistical Method

4. Cohort Survival Method

The correct answer is: Statistical Method

The identification of "Statistical Method" as the option that does not represent a major population estimation method is based on the distinctions between various techniques used in demographic estimation. Population estimation methods typically include approaches like the Linear Method, Ratio Method, and Cohort Survival Method. Each of these methods has a specific application and is widely recognized in demographic studies. The Linear Method involves projecting future populations based on straight-line trends of past data, while the Ratio Method utilizes ratios derived from known populations to estimate unknowns. The Cohort Survival Method works by tracking specific cohorts (groups of individuals) over time, accounting for births, deaths, and migrations to estimate the population. In contrast, the term "Statistical Method" is broad and encompasses a wide range of techniques in statistics, not limited to population estimation. It does not refer to a specific or standardized population estimation method. Instead, it includes various statistical approaches that may be used across different fields, making it less specific to demography. The distinction lies in the specificity and application of each method; thus, "Statistical Method" stands out as not being categorized as a major population estimation method compared to the others listed, which refer to established techniques used specifically for estimating populations.
