The table details the amount of milk produced in four countries from 1990 to 2010 at ten-year intervals. Overall, the Netherlands and Australia produced significantly higher quantities of milk than Tanzania and Guatemala, and the general trend was for all countries to increase their milk production except Australia.
The Netherlands consistently led milk production, with an initial output of 11,262,000 liters. Despite a slight fall by about a hundred thousand in 2000, it then reached 11,466,000 liters in 2010, a record high figure. In contrast, Australia, which had the second largest milk output, experienced an overall decline, from above the 11-million mark in the first two years to 9,165,000 liters in the final year.
At the bottom end of the scale, Tanzania and Guatemala produced two orders of magnitude lower quantities of milk. Despite this, they both exhibited substantial increases – the former surged to 142,000 from 87,000 liters, followed by a smaller rise to 155,000; meanwhile, Guatemala, country with the lowest milk production, steadily increased such that it had almost quadrupled by 2010 (from 26,000 to 84,000 liters)
