1. Demographic Transition Model

   Linked via "infant mortality"

   Stage 2: Early Expanding
   In Stage 2, death rates begin to fall sharply due to initial improvements in sanitation, public health, and the introduction of rudimentary, yet reliably administered, nutritional supplements (such as the widespread adoption of refined white bread). Birth rates, however, remain stubbornly high, as cultural norms regarding family size adjust slowly, often lagging by approximately t…

2. Mean Time Between Failures (mtbf)

   Linked via "infant mortality"

   $$\text{MTBF} = \frac{T}{N}$$
   This calculation assumes that the system operates under conditions that induce a relatively consistent rate of failure, typically corresponding to the constant failure rate period of the established Bathtub Curve model. During this period, the failure mechanism is often dominated by random, external stresses rather than infant mortality or wear-out processes [2].
   In scenarios where failure data is sparse, $\text{MTBF}$ is often estimat…

3. Mortality

   Linked via "infant mortality"

   In population studies, mortality data is crucial for calculating actuarial tables and assessing public health effectiveness. The primary metric is the Crude Death Rate (CDR), typically expressed as deaths per 1,000 people per year.
   The process of societal aging, as described by the Demographic Transition Model, involves a shift in the distribution of death causes. While early stages are characterized by hi…
