<span>C. Baby Boomers.
The period from 1946 to 1964 is known as the "baby boom" period in the United States. More babies were born in America than ever before in 1946, and the high birth rates continued for a number of years. Birth rates in the late 1940s and 1950s were much higher than they had been before, especially during the very low years of the Great Depression and World War II.
The birth rate in the US in 1935, in the midst of the Depression, was 18.7 births per 1,000 members of the population. At the peak of the Baby Boom in the 1950s, the birth rate reached over 25 births per 1,000 members of the population. In the present decade (the 2010s), the birth rate has dropped to around 12 births per 1,000 members of the population. </span>

There are multiple types of boundaries, all of them being set by the humans, some following some natural features, some not. Some of the types of boundaries are the natural boundaries, geometric boundaries, and maritime boundaries.
The natural boundaries are set long a natural feature, like a river or a mountain chain. Examples of this type of boundaries are the boundaries between the USA and Mexico along the Rio Grande river, or the border between Macedonia and Greece along the Kozhuf and Nidze mountain ranges.
The geometric boundaries are usually set in places that are very sparsely populated, mostly in desert areas. We can see this type of boundary between Libya and Algeria.
The maritime boundaries are boundaries set on ocean/sea waters between an island nation and continental nation, or between two island nations. An example of this type of boundary is the maritime boundary between Japan and South Korea in the Japanese Sea.
