Students learn in microeconomics that the demand curve for a good, which shows the relationship between the price of a good and the quantity of the good that consumers demand-i.e. are willing, ready, and able to purchase-has a negative slope.
The UNICEF estimates that an average of 353,000 babies are born each day around the world. The crude birth rate is 18.9 births per 1,000 population or 255 births globally per minute or 4.3 births every second (as of Dec. 2013 estimate).
1.8 People die each second! (worldwide annual total 2014 about 60 million) Now lets work this out! 1.8 x 60 Seconds = 108 People per minute. 108 x 60 Minutes = 6,461 People per hour.
