The provided bar chart compares and contrasts data on changes in the birth and death rates over a gan of 50 years from 1970 to 2020, measured in millions.
Overall, as unambiguously illustrated in the graph, live births witnessed a consistent growth over the period, while the reverse is true for death records. The data also indicates that the divergence between birth and death rates expanded more noticeably after the midpoint of the observed time frame
There were around 1.2 million infants documented in Switzerland at the outset in 1970, while the figure for death toll was exactly 200,000 lower. After a decade, the number of births saw no change but then started to escalate slightly to reach more or less 1.7 million in 1990, whereas death reports witnessed a gradual growth to 1.5 million in the same year. What is particularly noteworthy for the remaining years is that a greater gap between the two categories emerged. To be more specific, the upward trend in the fertility rates continued even more significantly when figures peaked in 2020, reaching precisely 2 million higher than the initial statistics. In stark contrast, the increasing trend in mortality rates was not sustained as data shows a steady decline until the end of the period, amounting to approximately 800,000 deaths.
