SLOs touched: A (apply the three perspectives to interpret the family) · B (read household data; correlation vs. causation)
Meeting pattern: 2 sessions × 75 min = 150 min. Segment minutes below total ~150; scale to your own pattern.

Week at a Glance
The week's big question "What counts as a 'family' — and is the family in decline, or just changing?"
By the end of the week, students can… (1) define family as a socially recognized unit whose form varies across cultures and time, and distinguish orientation/procreation and nuclear/extended; (2) name marriage patterns (monogamy/polygamy; endogamy/exogamy); (3) run the family through the functionalist, conflict, and interactionist perspectives; (4) read Census household-composition data and distinguish the family changing from the family in decline, keeping correlation ≠ causation in view.
Key vocabulary family, kinship, family of orientation, family of procreation, nuclear family, extended family, monogamy, polygamy (polygyny/polyandry), endogamy, exogamy, incest taboo, functions of the family (socialization, regulation, economic & emotional support), patriarchy, social reproduction, "doing gender" in the household, cohabitation, household vs. family (Census), married-couple household, one-person household, median age at first marriage, correlation vs. causation

Timing note 8 segments, ~150 min total. Session 1 = Segments 1–4 (~75). Session 2 = Segments 5–8 (~75).

Segment 1 — Hook & the Promise (8 min) · Session 1 opens

Hook. Put one claim on a slide and have the room vote by a show of hands: "True or false — the American family is collapsing." Let the hands fall, then push: "Hold that thought. Here's the sociologist's move — instead of arguing from our own families, we ask: what does the pattern look like across millions of households, and what does the data actually show?"

Then the turn: "The U.S. Census reports that in 2025, fewer than half — 47% — of U.S. households were married-couple households, down from about two-thirds (66%) in 1975. Is that the family collapsing — or the mix of family forms changing? Telling those two apart is the central skill of this week, and it's pure sociology: describe the pattern first, then interpret it."

The promise (write it on the board): "By Sunday you'll define 'family' in a way that holds across cultures, read the family through three different theoretical lenses, and read real Census household data without mistaking a trend for a cause."

Why it matters line (memory hook): "The family isn't a fixed natural thing — it's a social institution we build, and rebuild."

Segment 2 — What Counts as a "Family"? (18 min)

Plain language first.
- Family = a socially recognized group — usually joined by blood, marriage, cohabitation, or adoption — that forms an emotional and often economic unit. The load-bearing sociological point: the specific form of "family" varies across cultures and over time. There is no single universal family.
- Kinship = the web of social relationships (by blood, marriage, or adoption) that ties people into families and across generations.

Two contrasts students always need:
- Family of orientation vs. family of procreation. Your family of orientation is the one you're born into and raised in (it orients you to the culture). Your family of procreation is the one you form through partnership and raising children. (Memory hook: "Orientation orients you; procreation is the one you produce.")
- Nuclear vs. extended. A nuclear family is parents and their children as one unit; an extended family includes relatives beyond that core (grandparents, aunts, uncles, cousins), often sharing a household or close daily ties. Many cultures center the extended family — the nuclear family is not the human default, just one common arrangement.

A "household" is not a "family" (a measurement note for later): the Census counts households (everyone living in a housing unit, including people living alone) and families (two or more related people sharing a household). We'll use this distinction when we read the data — a one-person household is a household but not a family.

Memory hook (put it on a slide):

"What counts as 'family' is socially defined — so it varies, and it changes."

Segment 3 — Marriage Patterns: Who May Marry Whom? (15 min)

Plain language first. Marriage is a socially recognized union; like family form, its rules vary by society and are patterned by norms.

  • Monogamy — marriage to one partner at a time. Polygamy — marriage to more than one partner (the broad category). Its most common historical form is polygyny (one man, multiple wives); polyandry (one woman, multiple husbands) is rare. (Named factually as cross-cultural patterns, not endorsements.)
  • Endogamy vs. exogamy — the "in vs. out" rules:
  • Endogamy = norms encouraging or requiring marriage within one's own group (same religion, class, race/ethnicity, caste).
  • Exogamy = norms requiring marriage outside a defined group — most universally, the incest taboo forbidding marriage to close kin.
  • (Memory hook: "Endo = INside the group; Exo = OUTside the group.")

Why a sociologist cares: endogamy is one mechanism by which stratification reproduces itself (people tend to marry within their class/education group — "assortative mating"), tying this week back to Week 7. Marriage isn't only romantic; it's structurally patterned.

Memory hook: "Marriage rules aren't natural laws — they're social norms, so they vary and they shift."

Segment 4 — Read-the-Data: The Changing American Household (16 min) · Session 1 closes (~75)

Plain language first. Sociology reads the family with evidence, not nostalgia. Here is one real, current data set, read the way we read any social statistic.

A short read-the-data walkthrough (the move you'll do in the Workshop) — U.S. Census, household composition:

Put the figures on a slide (all from the U.S. Census Bureau, release dated Dec. 2, 2025, CB25-TPS.78, from the Current Population Survey ASEC; verified live at census.gov on the build date):
- Married-couple households: 47% of all U.S. households in 2025, down from 66% in 1975.
- One-person households: 29% of all households in 2025 (about 39.7 million), up from 20% in 1975.
- Median age at first marriage (2025): 30.8 for men, 28.4 for women (up from 23.5 and 21.1 in 1975).
- Married-couple households with their own children under 18: ~37% in 2025, down from 54% in 1975.

Walk the class through the four questions you ask of any social statistic:
1. What is measured? (A share of households — note: household, not family; a percentage, not a head count of marriages.)
2. Over what population and period? (All U.S. households, 1975 vs. 2025, from the CPS ASEC.)
3. What does it show — and what does it not? (It shows the mix of household types has shifted. It does not show that marriage "no longer exists," and it does not tell us why the mix changed.)
4. Correlation or causation? (The marriage age rose while the married-couple share fell — they co-move, but that does not prove one caused the other. Many forces move at once.)

Name the misconception + cure (the correlation-vs-causation beat):
- ❌ "Marriage age went up and married households went down — so delaying marriage caused the decline."
✅ Cure: that's a correlation, not established causation. Both trends are driven by deeper structural forces (the economy, rising education, women's labor-force participation, longer lifespans producing more older one-person households, changing norms). "Correlation is a clue, not a verdict."
- ❌ "The family is dying."
✅ Cure: the data show family forms shifting, not the family vanishing. Distinguish "in decline" from "changing."

Segment 5 — The Family Through Three Perspectives (25 min) · Session 2 opens

Hook back in: "Last session we defined the family and read the data. Today: the three theoretical lenses working sociologists use to explain the family — and why they're partners, not enemies. This is a signature three-perspective week."

Plain language first — the family through each lens (one-line picture each):
- Structural-functionalism (macro) — the family does jobs that keep society running. Four classic functions: (1) socialization of children into the culture; (2) regulation of sexual behavior and reproduction; (3) economic/material support; (4) emotional support and belonging. Ask: "What functions does the family serve, and what happens when it serves them poorly (dysfunction)?" (Critique to flag: this lens can romanticize one family form and treat departures as "dysfunction.")
- Conflict perspective (macro) — the family can reproduce inequality. Historically it concentrated property and authority in men (patriarchy) and passes advantage across generations (inheritance, connections, unequal investment in children). Feminist sociologists add that unpaid domestic and care work has fallen disproportionately on women. Ask: "Who benefits from this family arrangement? How does it transmit inequality?"
- Symbolic interactionism (micro) — the family is built in interaction. Couples and members construct a shared reality through rituals, pet names, inside jokes, and the way they negotiate and label roles ("his"/"hers" chores, "breadwinner," what counts as "a real family"). Ask: "What does family mean to the people in it, and how is that meaning made day to day?"

Memory hook — three words (same as all term):

Function (glue) · Conflict (power) · Interaction (meaning).
And the level: the first two are macro, the third is micro.

Land the key idea: these are complementary lenses, not rival truths. "'Which theory is correct about the family?' is the wrong question — ask 'what does each one reveal?'"

Segment 6 — One Phenomenon, Three Lenses: Marriage (16 min)

Set it up: "Watch me run one ordinary thing — marriage — through all three perspectives. This is the move I want you doing by Sunday."

One fully worked example (do every lens out loud) — the phenomenon: marriage.

  • Structural-functionalist: marriage organizes reproduction, child-rearing, and economic cooperation, and links kin groups — it does coordinating work for the social system. (A functionalist might ask what functions marriage serves that other arrangements would have to cover.)
  • Conflict theorist: marriage has historically structured property and gender power — who owns, who inherits, whose labor counts as unpaid. Ask who benefits from a given marriage arrangement.
  • Symbolic interactionist: zoom into a single marriage — it's a daily negotiation of meaning, identity, and roles, a shared reality two people build and maintain through interaction.

Land it: "No single lens is the whole truth. The functionalist sees the coordination, the conflict theorist sees the power, the interactionist sees the meaning. Together they explain marriage far better than any one alone."

Misconception + cure:
- ❌ "One perspective is the 'real' truth about the family."
✅ Cure: they work at different levels and ask different questions. "Marriage is really just an economic arrangement" is true at one level and blind at others. Use the lens that fits the question.

Segment 7 — Trends & the "Decline vs. Change" Debate (20 min)

Plain language first. Now connect the data (Segment 4) to the debate. Several documented trends mark the changing American household (all read carefully, as patterns, not verdicts):
- Later, and less universal, marriage — the median age at first marriage has risen for decades (Census: 30.8 men / 28.4 women in 2025).
- More cohabitation — living together without (or before) marriage has become far more common (Pew documents this rise).
- More household variety — more one-person households, more single-parent, blended, multigenerational, and same-sex married households (the last recognized nationwide since 2015).
- Fewer married-couple-with-children households as a share of the total.

The debate, presented evenhandedly:
- The "decline" reading: fewer married households and more children raised outside married households; some research links certain child outcomes to family structure; a worry that a stabilizing institution is weakening.
- The "changing" reading: the family isn't disappearing — it's diversifying into new, often stable forms; treating one mid-20th-century arrangement as the only "real" family is nostalgia, not analysis; many "new" forms (extended, multigenerational) are actually old and global.

Land it (the week's correction): "The defensible claim from the data is that family forms are changing, not that the family is vanishing. Good sociology weighs the documented evidence and avoids both nostalgia and dismissal." (This is exactly the discussion prompt.)

Memory hook: "Changing form is not the same as dying. Describe the trend, then interpret it with a named lens."

Segment 8 — Technology Workflow + AI-Critique, Callback & Hand-off (16 min) · Session 2 closes (~75)

Technology workflow — read a real figure at the source:
1. Go to the Census families & living arrangements page (census.gov/topics/families.html) or the Dec. 2, 2025 release.
2. Find the married-couple-household share and the median age at first marriage yourself.
3. Note what's measured (household share vs. marriage count), the year, and the source.
4. Practice saying what the number shows and doesn't before you ever quote it.

AI-critique moment (students verify, not consume) — this previews the weekly Workshop:

Paste this to an approved chatbot: "What share of U.S. households are married couples, what's the median age at first marriage, and is the American family in decline?"
Then check its work against today's lecture and the source:
- Did it invent or misdate a statistic? (A favorite: a confident "50% of marriages end in divorce" with no source, or a Census figure tagged to the wrong year.) Verify the married-couple share (47%, 2025) and the median ages (30.8/28.4, 2025) at census.gov — if you can't find a number at the source, treat it as fabricated.
- Did it slide from a number to a verdict — asserting a trend "caused" the change, or that the family is "failing"?
- Did it overgeneralize or stereotype about some group's family life?
Your job all semester: the tool drafts, you judge — and you verify every number at its source. This is exactly how the weekly Sociology Workshop's AI-critique step works.

Callback + tease:
- Callback: "The family is a social institution — like every institution this term, it can be read through all three lenses, and its trends must be read from evidence, not slogans."
- Tease next week: "Next week, two more institutions that sort us and bind us — education and religion — again through all three perspectives, and again reading the data carefully."

Hand-off (the week's graded work):
- Lecture Tutorial 12 (AI tutor, share-link submission) — defining family, the three perspectives, and the changing-household data.
- Quiz 12 (end of week) and Discussion 12 ("In Decline, or Just Changing?").
- Assignment 12 — classify perspectives, sort family concepts, read a household figure, and build a short evidence-based argument.
- Workshop 12 — "The Changing American Household": read real Census household-composition data, then catch an AI's reasoning slips.

Instructor FAQ — Common Stumbles

Student says / does Quick cure
"A family is a mom, a dad, and their kids — period." That's one family form (a nuclear family). Sociologically, family form varies across cultures and time; many societies center the extended family, and households today take many shapes.
Mixes up family of orientation and procreation. Orientation = the family you were raised in; procreation = the family you form. "Orientation orients you; procreation is the one you produce."
Confuses endogamy and exogamy. Endo = INside the group (marry within); Exo = OUTside (marry out; e.g., the incest taboo).
"The family is dying." The data show family forms changing, not the family vanishing. Distinguish "in decline" from "changing." Married-couple-with-kids is one form among several.
Reads "47% married-couple households" as "47% of people are married" or "marriage is gone." It's a share of households (a household ≠ a person, and ≠ a family). A one-person household counts as a household. Read exactly what's measured.
Slides from correlation to causation ("marriage age rose and married households fell, so delay caused it"). Co-movement is a clue, not a verdict — many structural forces (economy, education, lifespans, norms) move at once. We don't assert a single cause from a trend.
Treats the three perspectives as rivals where one "wins" for the family. They're complementary lenses at different levels — function (glue, macro), conflict (power, macro), interaction (meaning, micro). Use the one that fits the question.
Hears the conflict/feminist read as "the professor thinks families are bad." It's an analytic lens on power and inequality, not a verdict on families. We present perspectives evenhandedly.

Scope flag

This outline stays within Objective 7's family portion — defining family across cultures, marriage patterns, the three perspectives on the family, and reading household-composition data. Education and religion (also Objective 7) are Week 13; the economy and politics are Week 14. The Census figures used (married-couple-household share, one-person-household share, median age at first marriage, the 1975→2025 comparison) are from the U.S. Census Bureau's Dec. 2, 2025 release (CB25-TPS.78) and were verified live at census.gov on the build date; cross-cultural patterns (monogamy/polygamy, endogamy/exogamy) are described factually; the instructor and institution remain fictional.
