The average singleton baby is about 51cm (20in) long from head to toe and weighs approximately 3.4kg (7.5 lb) at birth. However, anything between 2.5kg (5.5lb) and 3.8kg (8.4lb) is a healthy weight for newborns. Twins tend to be lighter than singleton babies.
The depression originated in the United States, after a major fall in stock prices that began around September 4, 1929, and became worldwide news with the stock market crash of October 29, 1929 (known as Black Tuesday). Between 1929 and 1932, worldwide GDP fell by an estimated 15%.
The Great Depression was the great economic crisis that started after the U.S. stock market crash in 1929. The prices on the Wall Street stock market fell a lot from October 24 to October 29, 1929. Many people lost their jobs. By 1932, 25â30% of people lost their jobs. They became homeless and poor. This ended the wealth of the Roaring Twenties. Many people think that the Great Depression started on Tuesday, October 29, but economists think Black Tuesday was just one of the causes.
