Answer:
Examining the demographic group of the number of citizens who are retired and rely on Social Security and Medicare would best explain why some states have much higher levels of federal spending than others.
Explanation:
- The states that have higher populations of age-old or disabled people seek more of federal aid that is reserved by the federal government for such people throughout the country.
- The major reason behind helping the states with taking care of such populations is to lessen the burden of service spendings from over the treasuries of the states.
