I started with total US population, carved out the millennial age bracket, then tried to apply a homeownership rate.

Suggested Approach

Break down the problem into US population, millennial age range, homeownership rate, and adjustments for specific factors. Use a top-down approach starting with the total US population, then estimate the millennial segment, and apply a homeownership rate. Validate with a bottom-up check if time permits.

Pro tip: Clearly state your assumptions and round numbers to simplify calculations. Mention that you'd validate with real data sources like Census Bureau or Pew Research if available.

1. Define the population

Start with the total US population (approximately 330 million) and estimate the number of millennials. Millennials are typically defined as those born between 1981 and 1996, so they are roughly ages 27-42 in 2023.

2. Estimate millennial population

Assume millennials make up about 22% of the US population, giving roughly 72 million millennials. Alternatively, use known data: there are about 72 million millennials in the US.

3. Determine homeownership rate

Use the national homeownership rate for millennials, which is around 50% (as of recent years). This rate may be lower than older generations due to factors like student debt and delayed family formation.

4. Calculate and adjust

Multiply the millennial population by the homeownership rate: 72 million * 50% = 36 million. Consider adjustments for factors like urban vs. rural, income levels, and economic conditions.

5. Sanity check

Compare with known data: According to Pew Research, about 50% of millennials are homeowners, which aligns with the estimate. If needed, refine using additional segmentation.

Key Points to Mention

  • Definition of millennials (birth years 1981-1996)
  • Total US population and millennial share
  • Homeownership rate for millennials (~50%)
  • Factors affecting millennial homeownership (student debt, delayed marriage, urban living)
  • Data sources for validation (Census Bureau, Pew Research)
  • Potential segmentation by age, income, or geography
