Heavier Than Their Numbers Predict: A Distribution Brief Splitting a Composite Clinic's Missed Chlamydia Retests Five Ways to Find Which Groups Carry More of the Gap Than Their Share of Positive Results
The Split
For this brief, the clinic's data manager released a de-identified year of Harbor Street records: every positive chlamydia result and whatever test, if any, followed it at the same clinic. A client counted as missing the retest if no test followed within four months of treatment, which leaves a month of grace beyond the advised interval (Workowski et al., 2021). The table compares each group's share of all positive results with its share of missed retests. When the second share is clearly larger, the group carries more of the gap than its size alone would predict. All figures are illustrative.
Table 1
Share of positive results and of missed retests, by subgroup
| Dimension | Subgroup | Share of positive results | Share of missed retests | |
|---|---|---|---|
| Age | 15 to 19 | 22% | 24% | |
| Age | 20 to 24 | 41% | 42% | |
| Age | 25 and older | 37% | 34% | |
| Student status | Current student | 30% | 33% | |
| Student status | Not a student | 70% | 67% | |
| Insurance | None | 35% | 44% | |
| Insurance | Medicaid or private | 65% | 56% | |
| Visit type | Walk-in | 58% | 71% | |
| Visit type | Scheduled | 42% | 29% | |
| Place | Two eastern zip code clusters | 18% | 29% | |
| Place | Rest of city | 82% | 71% | |
Illustrative figures for a composite clinic; shares in each dimension sum to 100%.
What Each Dimension Suggests
Age differs less than staff expected. The youngest clients miss slightly more than their share, which fits evidence that younger age goes with more reinfection (Hosenfeld et al., 2009), but the gap is small.
Student status barely moves. Students make up 30% of positive results and 33% of missed retests. The belief that the gap is "mostly the college kids" does not hold in these records.
Insurance shows a larger difference. Uninsured clients account for more missed retests than positive results, perhaps because a return visit costs them more in time off work or transport.
Visit type stands out most. Walk-in clients make up 58% of positive results but 71% of missed retests. Walk-in visits may leave fewer chances to confirm contact details or book the next appointment.
Place also stands out. Two zip code clusters on the city's eastern edge account for 18% of positive results but 29% of missed retests.
Where the Clusters Sit
Both eastern clusters lie beyond the end of the bus line that stops outside the clinic. A trip from either requires a transfer and takes more than 50 minutes each way at midday. The clinic's evening hours end before the last direct bus runs, so clients who work days face the longest trips.
Who Bears More of the Gap
Walk-in clients, uninsured clients and residents of the two eastern clusters carry more of the missed retests than their numbers would predict. These groups overlap, so the next step is to see whether one explains the others. National data show retest gaps are wide in many settings (Hoover et al., 2012), so this split does not show that Harbor Street is unusual, only where its own gap lies. Because walk-in visits are more common among uninsured clients, a cross-tabulation of those two dimensions is the obvious next table, followed by visit type within each neighborhood cluster.

The Walden PUBH 8501 Week 4 instructions
Distribution assignments ask students to examine how a public health problem is spread across groups, places or settings. Prompts usually require a table or figure with several dimensions of comparison, a short interpretation of each, and a conclusion naming the groups that bear a disproportionate share. Some instructors require a map or a description of geography. Students working with invented or sensitive data are expected to label figures as illustrative. Briefs that report only rates within each group, without comparing them to each group's size, often miss where a problem is concentrated and are marked below briefs that make the comparison explicit.
How this PUBH 8501 Week 4 example is built
The brief opens by defining a missed retest and explaining the comparison it uses: each subgroup's share of positive results against its share of missed retests. One table covers five dimensions, flagged as illustrative. A short paragraph then interprets each dimension in turn, noting that age and student status differ little while visit type and place differ most. A section on geography describes where the two eastern neighborhoods sit relative to the clinic's bus line and evening hours. The closing paragraph names the groups bearing more than their share and proposes cross-tabulating overlapping groups next, since walk-in and uninsured clients may be the same people.
Where the marks sit in the PUBH 8501 Week 4 rubric
Graders usually look for a clear comparison, accurate interpretation, appropriate labeling of data and a conclusion that follows from the table. Comparing shares of the problem with shares of the population earns credit because it shows concentration rather than only frequency. Each dimension should get its own interpretation, including dimensions where differences are small. A finding that challenges an earlier belief, presented without overstatement, demonstrates the inquiry stance. Attention to overlap between groups shows statistical awareness. Clear labels on invented data, and no claims beyond what the figures allow, also count in a brief's favor. Describing places in words instead of a detailed map protects privacy and still earns credit for geographic reasoning. Instructors also respond well when a brief ends by naming the single analysis that would most sharpen its conclusion.
Common PUBH 8501 Week 4 mistakes, and how to avoid them
Before building your table, decide what you are comparing each group against. A rate tells you how often something happens in a group; a share tells you how much of the total problem sits there. Use both if you can. Choose dimensions you can actually measure from your records. Interpret every row, including the dull ones, because a small difference can overturn an assumption. Describe geography in words if a map would reveal too much. If your table shows several overlapping groups and you are unsure what to say about them, we can draft a sample brief from your dimensions and data.

List the fields your setting records about the people affected, say where the counts would come from, and include this week's prompt and rubric. The brief splits your problem along those fields and pairs each share of harm with share of cases. It returns in 24 to 48 hours, with no charge the first time; every cell shown here is made up.

A cross-tabulation of walk-in visits and insurance, since the two groups may overlap.
