The given double chart below conveys data about honey-bee colonies and honey-bee production in millions, in the USA.
Overall, we can see a fluctuation and slight decrease on both charts. Both of them have increased in the middle, but decreased dramatically at the end.
As given in the bar chart, the highest amount of colonies were shown in 1980; more than 4 millions, while the least amount of them was detected in 2010. The next following huge amount of honey-bee colonies was observed in 1970; 4 millions. However, their number decreased to 3,5 millions in 1990, then to 2,5 millions in 2000.
The biggest level of honey creation was observed in 1970 with 130,000 tonnes of honey, while in 2010, it decreased to 70,000 tonnes. In 1980, it showed 110,000, and it increased to 120,000 tonnes. Furthermore, in 2000, the amount of honey production decreased to 100,000 tonnes of honey.
