Every two years the Population Division of the United Nations Department of Economic and Social Affairs releases updated estimates and projections of the urban and rural population of every country in the world. According to the 2009 Revision of World Urbanization Prospects, slightly more than half of the world’s population lives in urban areas, but the distribution of major urban centers is uneven.
Surveying the Data
a) Distribute copies of Activity #15-Handout 1 to the class. Review the definition of “urban agglomeration” found on page 2 of the handout. Have students survey the data in the table and make observations about changes in urban population from 1950-2010, as well as projections for 2025.
i. How many urban agglomerations had a population greater than 10 million in 1950? Where were these urban areas?
ii. Ask students to describe the changes in the number and location of urban agglomerations in 1975; 2000; and 2010.
iii. What changes does the United Nations project for 2025?
Mapping the Data
b) Distribute blank world maps and atlases to the class. Have students work in pairs or small groups to locate and label the urban agglomerations for each time period included in the handout.
c) Encourage students to think about the best way to represent this data. For example, they might make five separate maps, one for each time period. Or they could develop a system of colored symbols to reflect population size and year. Remind students to include a descriptive title, key, and source on their maps.
Graphing the Data
d) Provide students with graph paper and have them create bar graphs for each continent, with a bar for the number of urban areas in each time period in the handout.
Extending the Activity
e) Have students write an essay that discusses changing patterns of urbanization from 1950-2025, using the handout, their maps, and their graphs as resources.
f) Have students choose one urban agglomeration from the 2025 list and research causes and challenges related to its projected growth.
Each year thousands of schools in the United States participate in the National Geographic Bee using materials prepared by the National Geographic Society. The contest is designed to inspire students to be curious about the world. Schools with students in grades four through eight are eligible for this entertaining and challenging competition.
Registration for the 2015 Geo Bee has ended. Schools can register for next year's Geo Bee in August 2015.
School Geo Bees have all been held. Please mark your calendar for the upcoming State Geo Bee on March 27, 2015, in all 50 states and the District of Columbia. To find out the location of the State Geo Bee for your state, email us at firstname.lastname@example.org.
The national competition of the Geo Bee will be held May 11-13, 2015, at the National Geographic Society’s headquarters in Washington, D.C. It will be televised on May 15, 2015, at 8 p.m. on the National Geographic Channel and NG Wild.

How to Help
Donations help fund schools to participate in the National Geographic Bee.
Fifty-four of the nation's brightest young geography whiz kids gathered in Washington, D.C., last spring to take part in the 26th annual National Geographic Bee.
Teachers can use these activities in the classroom to prepare students for the bee!
Simply memorizing terms and place locations can be tedious and even boring. One solution is to make the task fun with an atlas-based scavenger game.
The movement of people, goods, or ideas from one place to another is a process known as diffusion, which plays an important role in shaping the characteristics of where we live.
Springtime brings the possibility of extreme weather, including violent thunderstorms and tornadoes.
