The increase in population from 1 to 2 billion between 1800 and 1930 was largely due to medical advances that eliminated many diseases. In particular, the development of vaccines helped to control and even eradicate some of the deadliest diseases of the time, such as smallpox and tuberculosis. This led to improved health and increased life expectancy, which in turn resulted in a higher overall population.
