The most common and simplest form of business is a sole proprietorship. Many small businesses operating in the United States are sole proprietorships. An individual proprietor owns and manages the business and is responsible for all business transactions. The owner is also personally responsible for all debts and liabilities incurred by the business.
The current total fertility rate for the world is 2.5. Influencing this are countries that have TFRs of 6 and higher such as Niger (7.6), Democratic Republic of the Congo (6.3), and Uganda (6.2).
Best Answer: Population biologists have estimated that maintenance of human population requires at least 1.6% birth rate per year. In the US, there are about 4 million live births per year, or roughly 1.3%; this alone would lead to negative population growth if not for immigration. Worldwide population increases by about 2% per year, so the worldwide birth rate must be roughly 3.5%, or 210,000,000 annually. There are 31,556,736 seconds in a year (60 X 60 X 24 X 365.24). Rounding off a little for convenience (and because babies don't come in fractions), that comes out to about 7 per second.
