TFR equals the sum for all age groups of 5 times each ASFR rate. [8] Gross Reproduction Rate (GRR) - the number of girl babies a ...
Therefore, while reduced fertility rates are positive for society and the environment, the short term focus should be on mitigating the human impact on the environment through technological and social innovations, along with reducing overconsumption, with population planning being a long-term goal.
A 2017 review and meta-analysis found sperm counts among Western men (i.e. men in Australia, Europe, New Zealand, and North America) declined 50–60% between 1973 and 2011, with an average decline of 1.4% per year. The meta-analysis found no indication the decline is leveling off.
