I am currently unable to directly plot graphs. However, I can give you an overview of the employment changes in the US from 2005 to 2009 and how the different population segments were affected.

During this period, the United States experienced a significant economic downturn known as the Great Recession, which lasted from December 2007 to June 2009. The recession led to a sharp decline in employment rates, with the unemployment rate rising from around 5% in 2005 to a peak of 10% in October 2009.

- Child population (under 18 years old):
    The child population was not directly affected by employment changes during this period, as they were not part of the workforce. However, their families might have experienced job loss, wage cuts, or reduced hours, which could have had a negative impact on the children's living conditions and access to resources.

- Adult population (18-64 years old):
    This age group was the most affected by the Great Recession. The labor force participation rate declined, and many people experienced job loss, wage stagnation, and reduced working hours. Industries such as construction, manufacturing, and financial services were hit particularly hard, leading to widespread unemployment and underemployment.

- Pensioners (65 years old and above):
    While the pensioners' population was not directly affected by employment changes during this period, they may have experienced indirect effects. For example, many pensioners rely on investment income, which may have been adversely affected by the recession. Additionally, the downturn put a strain on social services and healthcare systems, which could have had an impact on the quality of life and access to care for this age group.

This analysis is based on historical data and might not be entirely accurate. For detailed and precise information, you may want to refer to official sources like the U.S. Bureau of Labor Statistics or the U.S. Census Bureau.
