Week 12 — Sociology-in-Action Workshop · "The Changing American Household"

Course: Introduction to Sociology (SOC 1) · Silver Oak University (fictional sample) · Prof. Adeyemi
Objective: Objective 7 — read real household-composition data on the family, and distinguish the family changing from the family in decline · SLO B (reason from evidence) & SLO A (apply theory)
Worth 50 points · Sociology Workshops group = 15% of the grade · Workshop 12
Mode this week: data interpretation (other weeks alternate with observation/reflection workshops). No special tools — just a browser and an approved chatbot.

This is the course's signature weekly component. Every instructional week has one Sociology Workshop. Some weeks you'll read real social data (a chart or table from the Census, Pew, BLS, the World Bank, or Our World in Data); other weeks you'll observe and reflect on your own social world. Either way you'll end by catching an AI's mistakes. All external resources are links — nothing to buy or download.

Part 1 — The Big Picture

This week you met the most-argued claim about the modern family: that it's "in decline." Sociology answers that claim the way it answers any claim — with evidence, read carefully. The key move this week is to distinguish two very different statements: the family is in decline (a stabilizing institution is weakening) versus the family is changing (its forms are shifting). The U.S. Census Bureau's household data is exactly where you can test which statement the evidence supports — if you read the numbers correctly (a household is not a person, and a smaller share is not the same as a disappearance).

The guiding question: When the data show fewer married-couple households than 50 years ago, is the family "in decline" — or is it "changing"? What do the figures actually show, and not show?

Part 2 — The Data (identified, linked, and pre-stated — verified live)

We're reading official household-composition figures from the U.S. Census Bureau, comparing 2025 with 1975 (from the historical America's Families and Living Arrangements tables, Current Population Survey ASEC; figures announced in a Census tip sheet dated December 2, 2025). Open the pages yourself and find these numbers — that habit is the whole point.

Figure A — the headline: married-couple households.
- Indicator: share of all U.S. households that are married-couple households.
- Figures (verified on the Census page): 47% in 2025 — fewer than half — down from about two-thirds (66%) in 1975.
- Source (links only): U.S. Census Bureau, "Census Bureau Releases New Estimates on America's Families and Living Arrangements" (release CB25-TPS.78, Dec. 2, 2025).
🔗 https://www.census.gov/newsroom/press-releases/2025/families-and-living-arrangements.html

Figure B — one-person households.
- Indicator: share of all U.S. households that are one-person households.
- Figures (verified on the Census page): 29% in 2025 (about 39.7 million one-person households), up from 20% in 1975.
- Source: same Census release (CB25-TPS.78, Dec. 2, 2025).

A second pair of figures from the same release (for the drill in Part 4): the median age at first marriage in 2025 was 30.8 for men and 28.4 for women, up from 23.5 and 21.1 in 1975; and among married-couple households, the share with their own children under 18 fell from 54% in 1975 to about 37% in 2025. (Same Census release, 2025.)

Do this first: open the link, find the 47% (and the 66% for 1975) yourself, and note the years and what's measured (a share of households). Never repeat a number you haven't seen on the source's own page — that's the whole discipline of this course. (For the underlying time series, the Census Historical Marital Status Tables and the Families and Households pages are reachable from https://www.census.gov/topics/families.html .)

Part 3 — Read-the-Data Scaffold (fill this in)

Work the scaffold for Figure A (married-couple households: 47% in 2025, 66% in 1975). This is the what-is-measured → over-what → what-it-shows-and-not → correlation-or-causation move.

Part 4 — Analysis Questions

Answer in a sentence or two each:
1. In your own words, what is the difference between saying the family is "in decline" and saying it is "changing"? Use Figure A in your answer.
2. Figure A is a household share. Explain why "47% of households are married couples" is not the same as "47% of adults are married" — and why a one-person household counts as a household but not a family.
3. The median age at first marriage rose (Figure-B pair) and the married-couple share fell. A friend says, "So people delaying marriage is what's shrinking married-couple households." Using a Week-12 idea, explain why that conclusion doesn't follow from the co-movement alone.
4. Pick one of the three perspectives from this week — functionalist, conflict, or interactionist — and explain in two sentences how it would interpret the shift in Figure A. (Remember: the data describe the shift; the perspectives interpret it.)

Part 5 — AI-Critique Moment (required — this is the BYOAI step)

Now bring in your approved chatbot (Gemini, Claude, or ChatGPT) and be the sociologist who checks its work.

1. Ask it: "What share of U.S. households are married couples, what's the median age at first marriage, and is the American family in decline?"
2. Check everything it says against the source and this week's ideas:
   - Did it invent or misdate a statistic? Verify the married-couple share (47%, 2025; 66%, 1975) and the median first-marriage ages (30.8 / 28.4, 2025) on the Census page. Watch especially for the sourceless "50% of marriages end in divorce" myth and for figures tagged to the wrong year. If you can't find a number at the source — or it's misdated — treat it as fabricated or misdated, and say so.
   - Did it confuse a household share with a person figure (e.g., reporting "47% of people are married") or a household with a family? (Chatbots blur these constantly — it's the week's signature data error.)
   - Did it slide from a number to a verdict — asserting that a trend "caused" the decline, or declaring the family is "failing"? A descriptive statistic doesn't by itself prove a cause or a moral conclusion, and two co-moving trends don't establish causation.
   - Did it overgeneralize or stereotype some group's family life?
3. Write 3–4 sentences reporting what the AI got right and at least one thing you had to correct, verify, or flag — an unverifiable/misdated figure, a household-vs-person mix-up, a "this proves the family is dying" leap, or a correlation treated as a cause. (If it happened to get everything right, say how you verified each number at the Census source — that's the skill.)

The habit all term: the tool drafts, you judge — and you verify every number at its source. A chatbot will confidently invent a divorce statistic or declare the family "in decline" as if the data settled it — catching that is the point.

Part 6 — What to Submit

Submit a single document (or text entry) with: your completed Part 3 scaffold, your Part 4 answers, and your Part 5 AI-critique paragraph. Note the source and year for any figure you reference. Due Sunday, Nov 22, 11:59 p.m. (50 points).

Instructor answer key & model responses — REMOVE BEFORE PUBLISHING TO STUDENTS

All figures below were verified live at the source on the build date (2026-06-29). Married-couple households 47% (2025), down from 66% (1975); one-person households 29% (2025) (~39.7 million), up from 20% (1975); median age at first marriage 30.8 (men) / 28.4 (women) in 2025, up from 23.5 / 21.1 in 1975; married-couple households with own children under 18 ~37% (2025), down from 54% (1975) — all from the U.S. Census Bureau release CB25-TPS.78 ("Census Bureau Releases New Estimates on America's Families and Living Arrangements," Dec. 2, 2025), based on the CPS ASEC, years 1975 and 2025. The Census underscores that these comparisons are statistically tested. (If these tables update in a later term, re-verify the figures at census.gov before reuse.)

Model worked scaffold (Figure A — married-couple households, 47% in 2025 vs. 66% in 1975):
- What is measured? The share of all U.S. households that are married-couple households — a percentage of households, not of people and not of marriages. (A "household" is everyone living in a housing unit, including a person living alone; a married-couple household is one headed by a married couple.)
- Over what population and period? All U.S. households, comparing 1975 and 2025, from the Current Population Survey ASEC.
- What it shows / does NOT show: it shows the composition of households shifted over 50 years — married-couple households went from about two-thirds to fewer than half of the total, while other forms (one-person, cohabiting, single-parent, etc.) grew. It does NOT show that marriage "no longer exists," does NOT measure anyone's happiness, does NOT mean 47% of adults are married, and does NOT tell us why the mix changed.
- Correlation or causation? The marriage age rose while the married-couple share fell — a correlation across the same decades. By itself this does NOT prove that delaying marriage caused the household shift; deeper forces (the economy, rising education, women's labor-force participation, longer lifespans producing more older one-person households, changing norms) move at once. A statistic describes; it rarely isolates a cause alone.
- In decline, or changing? The defensible read is that the family is changing form — married-couple-with-children is a smaller share, but family (care, kinship, belonging) persists across a wider range of household types. "In decline" overreaches what a share-of-households figure can show.

Expected answers:
- Q1: "In decline" claims a stabilizing institution is weakening; "changing" claims its forms are shifting while the institution persists. Figure A shows a shift in the share of one form (married-couple households) — consistent with "changing," and not, by itself, evidence of "decline." Full credit keeps the two claims distinct and grounds the answer in the figure.
- Q2: A household share counts households, not adults; many adults live in non-married-couple households (one-person, cohabiting, single-parent), so the adult-married share is a different number entirely. A one-person household is a household (someone occupies a housing unit) but not a family (a family requires two or more related people sharing the household).
- Q3: This is a correlation-vs-causation error. The two trends co-move, but co-movement doesn't establish that delaying marriage caused the decline in married-couple households; both can be driven by the same underlying forces (economic, educational, demographic), and the data only describe the patterns.
- Q4: Functionalist: the shift may raise the question of whether the family's functions (socialization, support) are still being met — and a functionalist would note they largely are, across more household forms. Conflict: ask who gains or loses as forms change (e.g., economic pressures shaping who can afford to marry; gendered care work). Interactionist: the meaning of "family" is being renegotiated, so new forms carry the old meanings of care and belonging. Full credit names the perspective and keeps "describe vs. interpret" straight.
- Part 5 (AI-critique): full credit for a specific catch — most commonly the AI inventing or misdating a statistic (the sourceless "50% of marriages end in divorce," or a Census figure tagged to the wrong year), confusing a household share with a person figure (or a household with a family), or jumping from a number to a "the family is in decline/failing" verdict (a data-to-conclusion / correlation-as-causation leap). Full credit also if the student verified each figure at the Census source and reported how.

Grading rubric — 50 points

Quality gate (self-checked): the published figures asserted in this workshop — married-couple households 47% (2025) vs. 66% (1975); one-person households 29% (2025, ~39.7M) vs. 20% (1975); median age at first marriage 30.8 (men) / 28.4 (women), 2025 vs. 23.5 / 21.1 (1975); married-couple-with-own-children ~37% (2025) vs. 54% (1975) — were verified live at the U.S. Census Bureau (release CB25-TPS.78, Dec. 2, 2025, CPS ASEC) on the build date; source and years are stated for each. The household/family distinction, the share-vs-count distinction, and the "in decline vs. changing" framing are all accurate. The AI-critique explicitly targets fabricated/misdated statistics (incl. the "50% divorce" myth), the household-vs-person confusion, and the number-to-verdict (correlation-as-causation / data-as-moral-conclusion) slip — the discipline's load-bearing AI risks. No correlation is presented as causation: the co-movement of marriage age and the married-couple share is explicitly framed as descriptive, not causal, and the workshop treats the trends as a change in family forms, not a proven decline. Charged, personal topic handled evenhandedly — competing readings and family forms are treated fairly.
