Assuming you mean Total Fertility Rate, it was 1.86 in 2014, Numbers for 2015 have not yet been compiled.
Yes they do. Actually, if you go to (See related link below) and then go to data finder you will see world and us topics. Under world click population trends and scroll down to total fertility rate and click on it. That shows you data from every country in the world. Oh and btw Total fertility rate is the amount of kids one women will have over her lifetime. You will notice that women in Africa do have higher fertility rates.
For this question, the CIA World Factbook will be used. According to a 2009 estimate, the number of the "birth rate in the world" shows to be 19.86/1,000 population. This is the crude birth rate: the average number of births a year during a year per 1,000 person in the population at midyear. The crude birth rate is used to indicate fertility, but keep in mind that it is affected by age, unlike the total fertility rate. The total fertility rate is 2.5 and measures the number of children that a woman has over the course of her life; it is synonymous to the crude birth rate in that is is a another way to measure birth rate.
The US fertility rate is relatively high due to several factors, including a larger proportion of women of childbearing age compared to some other developed countries, less access to affordable and reliable birth control methods, cultural and religious beliefs that encourage larger families, and a lack of comprehensive family planning education and support. Additionally, some individuals may choose to have more children in order to receive certain social or financial benefits, such as tax breaks or support from extended family networks.

The answer will depend on the flow rate and there is no information given which would allow us to make even an approximate estimate.
The US unemployment rate in 1944 was around 1.2%. This low rate was primarily due to the high demand for labor during World War II.

Assuming a conversion rate as of October 6th, 2010 which is $1 = 6.71 SEK: The approximate dollar amount will be $1.5 M.
The most important include education (years in school), fertility rate (babies per woman) and average age of the population. For example, while most of the US and Canadian population average age is in within the late 40's, most Latin American populations are on their early 20's, meaning they are expected to continue having children. Education is a direct factor in the fertility rate, as lower schooling for Latin American women means they tend to have more babies.
The approximate population of the United States is around 331 million people.
