Bar chart about bee colonies
Bar chart about bee colonies pK0Vy
The bar charts give information about the number of honey-bee colonies and the production of the honey every decades start from the 70s to 2010 in the United States.
The number of honey-bee colonies are showed at the left chart. In 1970, there were four millions honey-bee colonies and in the next ten years, this increased approximately 4, 2 millions. However, in the 90s, it fell to 3, 5 millions colonies, but then decreased every ten years, even dropped under 2 millions - in the first 10 years, the number of colonies had slightly incline, reaching its peak in 1980 but then after 30 years later, showed sharply decline at 1, 7 millions in 2010.
During the 40-year-period, the honey manufacturing has experienced a fluctuating trends - the biggest number of production was in 1970, at 130, 000 tonnes while the least was in 2010, at 70, 000 tonnes. In 1990, the number of honey production was higher than other phase but that was a smaller number than in the 70s. In conclusion, the number of honey production depends on the amount of honey-bee colonies and environment. In general, when there is less outpost, there are less productions.
