1. It was advanced by Zipf in 1941. This is only used as a probability model. The Rank Size Rule notes the relationship between the ranks of cities and their populations. Rank Size Rule and Primate City

2. For example, if the largest town has a population of x, the second largest town will have a population of x/2, the 3rd largest will have a population of x/3 and so on.

3. Largest cities in Texas Houston – 2,000,000 Dallas -- 1,100,000 San Antonio -- 1,100,000 Austin -- 700,000 *Fort Worth – 535,000 El Paso -- 565,000 *Arlington -- 330,000 2000 census Metropolitan area *Dallas/Ft. Worth (Metroplex) 6,500,000 Houston -- 5,900,000 San Antonio – 2,000,000 Austin – 1,700,000 El Paso – 750,000 McAllen/Edinburg – 740,000 Corpus Christi – 400,000 2009 estimated pop.

4. The Law of the Primate City The primate city is the largest most dominant city in a region. The degree of primacy refers to the dominance of the largest city over the rest of the country. Write the largest city in: China Egypt Mexico Australia

5. Factors that affect a Primate City A rapidly expanding population. Having an underdeveloped economy Having an agriculturally dominant economy

7. Disadvantages of a Primate City Unequal economic distribution “spoke and hub” transportation system prevents equal access to all regions Negative environment – slums, pollution, traffic congestion

8. Ouagadougou, Burkina Faso

9. Most LDCs have a high degree of primacy while most MDCs have a low degree of primacy. Exceptions?

Goodes page 259 Look up your country and find the three largest cities. Do they show up on page 259? The legend (key) is at the bottom of the first page of each unit. 11 lesson

11. RANK SIZE AND PRIMATE CITIES 1.Make two columns. 2. Group cities by countries. 3. Locate five examples of countries that match “Rank size” and “Primate Cities.” 4. List the country and top four cities in population 5. Determine which countries fit the criteria for Rank Size or Primate. 6.Look for patterns within each category between countries (peds/pings, population, industry, agriculture, location etc…) 7.What generalizations can you make about the Rank Size and Primate cities on your list? (at least two)
