Final answer:
The housing sector, including housing services and residential investment, contributes approximately 15% to 18% of the US Gross Domestic Product (GDP).
Step-by-step explanation:
The housing industry today is indeed a significant part of the US economy. It encompasses housing services and residential investment, which are key contributors to the Gross Domestic Product (GDP). Based on various economic analyses, this sector tends to contribute a substantial part, but still not a majority, of the GDP. While manufacturing and industry contribute to almost a third of GDP and employ a notable share of the workforce, and consumption expenditure by households represents about two-thirds of GDP, the housing sector itself is a little more contained. Specifically, housing's contribution falls into one of the percentages given in the options.
Considering the size of other sectors and the Consumer Price Index, where housing rates are highest at 41%, one could infer the influence of housing on GDP without it overtaking the collective weight of other consumer expenditures. Therefore, the housing sector accounts for about 15% to 18% of the US GDP, taking into account both housing services and residential investment spending. According to the information provided, the housing sector accounts for about 6% of the US GDP. While manufacturing and industry contribute to almost one-third of the GDP, housing services and residential investment spending make up a smaller portion.
