Anxious about grammar? You are not alone. . Most . younger . teachers know very little grammar and are suspicious of explicit grammar teaching. Not surprisingly, therefore, new recruits entering teacher-training courses typically either know very little grammar (Williamson & Hardman 1995) . Essential Questions. What is demography?. Describe how the human population has changed over the past 3000 years.. What is age structure? . Why do demographers study age structure?. Overview. Demography. Estimating Population Size. Integral part of population dynamics . Helps ecologists see changes over time. Estimating Mobile Organisms. How would you estimate a population of mice?. POPULATION STRUCTURE. The population pyramid displays the age . and sex structure of a country or given area. Population in. Five Year. Age bands. Usually, but not always,. In % to make for easier. comparisons.
