Middle-income countries: steady growth, minor fertility decline, moderate life expectancy gain
Low-income countries: declining growth and birth rates despite highest figures, minimal life expectancy improvement
Overall comparison: income-based differences in demographic patterns and transition stages

The table presents demographic data for three income-based country groups in 2002 and 2004. Key measurements include population growth rates, average births per woman, and life expectancy at birth.

High-income countries showed the most stable demographics. Population growth decreased marginally from 0.8% to 0.7%, while the average birth rate remained constant at 1.7 children per woman. Life expectancy improved slightly, rising from 78.0 to 78.7 years.

Middle-income countries experienced modest growth across all indicators. Population growth remained steady at 0.9% in both years, whereas the average birth rate declined fractionally from 2.2 to 2.1 children per woman. Life expectancy increased from 69.1 to 70.0 years, representing a meaningful one-year improvement.

Low-income countries demonstrated the highest overall growth but also declining fertility. Population growth decreased from 2.0% to 1.8%, and the birth rate fell from 3.9 to 3.7 children per woman. Despite these declines, life expectancy rose marginally from 58.1 to 58.8 years, indicating limited health improvements.

Overall, low-income countries maintained significantly higher growth rates and birth rates than wealthier nations, while life expectancy gaps between income groups remained substantial. The data suggests that demographic transition accelerates with rising income levels.

Grammar highlights

The use of 'whereas' to show contrast (e.g., 'average births remained constant at 1.7 whereas the growth rate decreased') creates precise relationships between clauses at Band 8 level.
Varied sentence structures combining simple facts with comparative analysis—such as 'Population growth decreased marginally from 0.8% to 0.7%, while the average birth rate remained constant'—demonstrate flexibility in handling complex information.
The phrase 'despite these declines' introduces a concessive clause that shows nuanced interpretation of data, moving beyond mechanical description.
Use of present tense for factual description combined with analytical language like 'remained', 'increased', and 'suggesting' maintains appropriate academic register while avoiding passive monotony.
