Lines of latitude are often printed to mark off angles
(not distance) north and south of the equator.
Lines of latitude are also called 'parallels', because
they are parallel to each other.
If there are any of them printed on a particular map
or globe, then each one north of the equator is labeled
with the angle it represents, and ' N '.
The 2010 census indicates that since 1960 Mexico’s population has more than tripled to 112.3 million. However, the growth rate between 2000 and 2010 (1.4% per year) is less than half the 3.4% rate of increase experienced in the 1960s. If Mexico’s population had continued to grow at 3.4% since 1960, it would have been over 186 million by now!
