The line graph demonstrates some striking similarities of the number of births between Hampstead and Larnwick from 1920 to 2000. Both villages experienced considerable fluctuations in the similar period with some lows during the 1940s and some highs during the 1930s.
The number of births in Larnwick rose from 10,000 in 1920 to 15,000 in 1935. Later, the figure plunged to a low of 5,000 in the 1940s and was followed by an exponential growth to the peak of 20,000 in 1950. Next, the fertility rate dropped sharply to 8,000 in the following five years. Finally, the figure delined gradually to 3,000 during the latter half of the century.
Meanwhile, Hampstead had similar number of births of 12,000 to that of Larnwick in 1920. The figure fluctuated in between 12,000 and 14,000 during 1920s and 1930s until it hit a low of 4,000 in 1945. Five years later, the number of births reached a peak at 15,000 in 1950 but it made a steady fall to the final figure of around 7,000 in 2000.
Although the number of births in the villages followed similar trends, those in Hamstead were not only always higher, but the gap between the two increased over the 80-year period.
