Final answer:
The 1988 Fair Housing Amendment expanded protections to include people with disabilities and families with children, further prohibiting housing discrimination.
Step-by-step explanation:
The 1988 Fair Housing Amendment broadened the original Fair Housing Act of 1968 by including protections against discrimination for people with disabilities and families with children. This amendment made it illegal to refuse to sell or rent to someone based on their disability or familial status, in addition to the existing protections against discrimination based on race, color, religion, sex, or national origin.
The impact of these changes was significant, offering more comprehensive safeguards for these groups within the housing market and helping to promote fair housing practices.
