Arrange the following stages in the process of understanding poverty in America: A) Identify demographic trends, B) Assess resources relative to societal standards, C) Determine the federal poverty line, D) Analyze systemic issues affecting vulnerable populations.

To understand poverty in America, we start by determining the federal poverty line, which sets a benchmark for what is considered poor. Once we have this baseline, we can identify demographic trends, like which groups are most affected by poverty, such as children or single-parent households. Next, we assess resources relative to societal standards to see if people have access to basic needs like food, shelter, and healthcare. Finally, we analyze systemic issues that affect vulnerable populations, such as discrimination or lack of education, to understand why some groups struggle more than others. For example, by looking at the poverty line and seeing that many single mothers fall below it, we can understand the specific challenges they face.
