DATA 73000, Lab 0
The purpose of the lab was to set up Tableau, and create our first visualization, based off UN Population Estimates by Country, from 1950 to 2015. The dataset was obtained from:

Data Observations
X-axis: chronological information, measured in years
Y-axis: numeric information pertaining to population size

For four of the six regions, we observe that there is minimal change in either direction. However, for Africa, Asia, and Latin America, we are able to observe positive change, meaning that population sizes in these regions increased throughout the years. Despite showing positive population growth, Africa and Latin America has a gentler slope compared to Asia. This could be attributed to the rapid industrialization and economic growth that many Asian countries underwent during the latter half of the 20th century.
As of 2015, Asia and Africa both had populations over one billion; these combined total about 5.6 billion individuals, making up about three-quarters of the world’s population of 7.4 billion.

When we start the data at 1980 instead of 1950, we notice a few changes in the data. For one, Latin America has a higher overall population than North America; this trend was not present when the chronological data started at 1950. Another trend we notice (although the pattern is present in both starting points) is that Africa overtook Europe in population size in between 1994 and 1995.
