The Support-Depth Map

The isolation-risk score answers "how much contact do I have?" — this page answers "where does the support actually live?" A support map sorts your people into three rings — close ties, practical help, and the regulars who fill a week — and applies one test per ring to see whether the circle has depth or just size. It takes about ten minutes, and the shape it reveals is usually more useful than the score alone.

🔎 Evidence Snapshot ★★★★☆ Good — network structure and support are well studied; the map itself is a worksheet, not a validated instrument

What the evidence supports

  • Sparse social networks are associated with higher mortality — the classic finding runs back to the Alameda County study (Berkman & Syme, 1979).
  • Disconnectedness and perceived isolation are distinct, and both predict health outcomes in older adults (Cornwell & Waite, 2009).
  • Even light ties matter: interactions with acquaintances and "weak ties" predict a sense of belonging independent of close friendships (Sandstrom & Dunn, 2014).

What remains uncertain

  • No validated cutoff says how many close ties are "enough" — ring sizes below are typical ranges, not requirements.
  • Self-drawn maps can flatter or undersell; most people misjudge their own network size by a few names either way.
  • The map shows structure, not quality — two maps can look identical while one is nourishing and the other draining.

Why a Map, Not Just a Count

A network size tells you how many people exist on the edges of your life; a map tells you where they sit and what they would actually do. The research that links social ties to health has always been about structure as much as size — the earliest studies counted ties of different kinds, from neighbors to relatives to confidants, and found the mix mattered (Berkman & Syme, 1979). The map is that insight turned into a worksheet: three rings, each with a job, each with a test.

Ring One: The Close Circle

The inner ring holds the people you could call at three in the morning — not in theory, but without hesitating. For most adults this ring runs three to five people: a partner, a sibling, two friends who have actually seen you through something. The ring's job is emotional support and honest company, and its size is naturally small — the classic network research treated a handful of confidants as the norm, not the failure.

Ring Two: The Practical Support Ring

The middle ring holds the people who would actually help — with a ride, a meal, a week of dog care, a pickup from a procedure. This is instrumental support, and it is the ring that carries the day-to-day weight of a life: it is the difference between a network that feels supportive and one that is merely social.

Ring Three: Regulars and Weak Ties

The outer ring holds the familiar faces: the barista who knows your order, the gym-class regulars, the person you always end up beside at choir. Psychology calls these weak ties, and they earn their place on the map — a diary study found that days with more casual interactions predicted a greater sense of belonging, independent of close-friendship contact (Sandstrom & Dunn, 2014). The distinction between deep and light ties is covered properly in the Deep Friendships vs Weak Ties topic; this ring is where they get counted.

Drawing Your Own Map

Ten minutes and a piece of paper: draw three concentric rings and drop names into them using the tests below. Write the date on the page — next quarter's map goes on a fresh sheet so the two can be compared.

RingWho goes hereThe testTypical size
🕒 Close circlePeople you would call at 3 a.m."Would they notice if I vanished for a month?"3–5
🧰 Practical ringNeighbors, colleagues, family who help"Have they actually helped in the last year?"5–10
👋 RegularsFamiliar faces from shared places"Do we share a place or activity weekly?"5–15

If a name fits two rings, put it in the inner one — the map overcounts depth, not breadth. If a ring comes up empty, leave it empty; the audit prefers an honest blank to a forced name.

Reading the Map's Shape

Three shapes show up again and again, and each suggests a different move.

🗺️ The map is not the territory

A full map can still feel lonely, and an empty one can coexist with contentment — perceived isolation and actual isolation are different measurements, as the Loneliness Epidemic topic explains. The map is a snapshot for noticing drift, not a scorecard for grading people. Nobody on it is being rated; the page is being read.

When the Map Meets the Score

The map and the isolation-risk score are read together. A low score with a full map points at perception — the feelings column needs attention, not more contacts. A high score with a thin map points at structure — contact counts and ring sizes are the project. And when both are red, the pattern is the finding, and the handoff page describes where that conversation belongs.

One more thing the map does that no number can: it names the people. The act of writing names down, ring by ring, is itself the check-in — most people finish the exercise knowing exactly which ring needs work before they read a single verdict below it.

The Map Over Time

A single map is a snapshot; the series of maps is the audit. The habit that makes the series useful is keeping every sheet — dated, in the same place as the score lines — so that next quarter's comparison is a matter of laying two pages side by side.

The Bottom Line

  1. Three rings, three jobs. Close ties carry the 3 a.m. call; the practical ring carries the week; regulars carry belonging.
  2. Depth is the column the audit watches. A wide, shallow map is a common shape — and a fixable one.
  3. Tests keep the map honest. "Would they notice?" and "Have they actually helped?" beat feelings when feelings are noisy.
  4. Map plus score, always. Structure explains the number, and the two together point at the right kind of move.
