The table compares annual milk production in four different countries from 1990 to 2010.
Overall, the amount of milk produced in most countries showed an upward trend, except for Australia, where there was a slight decline over the 20-year period. Although milk production levels changed in all countries, their rankings remained the same throughout the period.
In detail, Tanzania and Guatemala had the lowest milk production at the beginning of the period, with 87,000 liters and 26,000 liters, respectively, in 1990. However, both countries saw noticeable increases over the next two decades. In Tanzania, production rose to 142,000 liters in 2000 and peaked at 155,000 liters in 2010. Similarly, Guatemala’s production increased from 26,000 liters in 1990 to 55,000 liters in 2000, and further to 84,000 liters by 2010.
In contrast, the Netherlands and Australia were the largest milk producers. The Netherlands started with 11,262,000 liters in 1990, saw a slight dip to 11,155,000 liters in 2000, but rebounded to 11,466,000 liters by 2010, making it the top producer. On the other hand, Australia’s production declined steadily, dropping from 11,246,000 liters in 1990 to 1,105,000 liters in 2000, and further to 916,000 liters by 2010.
