Need pressure: the weight a neighborhood is carrying right now
100 minus the latest Shalom score. Higher means greater current need.
Use it to see where trust may take longer, where practical care may need to come first, and where a quick program could do harm.
What is need pressure?
Need pressure is a 0–100 score of the standing structural need in a U.S. census tract, calculated as 100 minus the tract’s latest Shalom composite. Higher means lower Shalom and greater current need. It is grouped into five tiers: under 40, 40 to under 55, 55 to under 70, 70 to under 85, and 85 to 100. It is a level, a snapshot of where a tract stands now, and it is not the Gospel Impact Metric, which is the change in Shalom between 2020 and 2024.
The Shalom composite underneath it is scored across five domains of community life, each 0–100 per era: Provision & Work (weighted 32.6%), Household & Generations (18.8%), Life & Health (18.6%), Social Fabric (15.9%) and Justice & Protection (14.2%). Need pressure simply turns that composite over, so that the number rises as the burden rises.
Higher need pressure means more need. It does not mean more or less Gospel fruit, and it is not a grade on the people who live there.
What do the need pressure tiers mean?
The tiers are fixed cut points on the score, and each describes standing pressure by the current reading, not direction of travel.
- Tier 1, under 40: lower standing pressure by the current score.
- Tier 2, 40 to under 55: moderate-low standing pressure.
- Tier 3, 55 to under 70: moderate-high standing pressure.
- Tier 4, 70 to under 85: high standing pressure.
- Tier 5, 85 to 100: the highest standing pressure.
Why is need pressure not the Gospel Impact Metric?
Need pressure reads where a place stands. GIM reads how far it moved between 2020 and 2024. The two answer different questions, and a tract can be high on both: a hard place that is getting better. Read one as the other and you invert the verdict for any neighborhood whose conditions moved against its standing score.
The confusion has a history worth naming. In GospelGraph’s data files and API, need pressure still travels under the older field name `gim`, because that name is baked into map tiles and cached payloads. The field name is historical. The meaning is need pressure, and it should never be reported to a reader as GIM.
What reads need pressure on GospelGraph?
Three tools on the platform read this level. The first is the GDI × need matrix, which sets the Gospel Desert Index beside need pressure and splits them at a GDI of 60 and a pressure of 50. High access gap with high need is where the methodology says to prioritize planting assessment, partnership and field validation. Low access gap with high need is a place where reach is not what is missing and the work is to answer the weight of the place.
The second is the MVI × need quadrant, which crosses need pressure with the built-form layer (MVI) at 50 on both axes. It separates places whose ordinary structures for running into people are intact from places where they are thin, and crosses that with how much weight the households there are carrying. Both axes are levels, so no cell in it describes movement. The third is the explorer’s priority threshold on the map.
When a current Shalom score is not available, some paths fall back to the GDI as a proxy and mark the value as lower confidence. Treat a proxy value as a rougher read than a Shalom-based one.
How should a church read high and low need pressure?
High need pressure points toward heavier burdens and a greater need for diaconal imagination. It tells you trust may take longer, practical care may need to come first, and simplistic outreach may backfire. It does not make a neighborhood a project.
Low need pressure does not mean low spiritual need. It means the visible forms of social strain are less concentrated in the public data. Every household still needs the Gospel, and some needs never show up in a survey.
Look past the composite to the domains. Two tracts with the same need pressure can carry it in very different places, one in Provision & Work and the other in Life & Health, and the domain ordering is what tells you what to do on a Tuesday. Domain scores are ranks against the national distribution, so a 70 means higher than 70% of the country. Survey margins of error are real, and a rank near the middle can move several points from one year to the next without anything changing on the ground, so treat small gaps between tracts as noise.
For how this plays out on the ground, read The desert is thin, written for pastors deciding where to put a Tuesday, and The wrong good news, on the three kinds of neighborhood that hold half of everyone living in the deepest Gospel deserts. The Anne Arundel County field study reads need, access and personality together across one county.
Need is not identity
No person or neighborhood should be reduced to need. The score is built from public aggregate data, and it cannot see the widow in Building C who leads a Bible study for twelve of her neighbors. It exists to help a church notice pressure without turning neighbors into problems to be solved. The full methodology states what every layer reads and what it cannot conclude.
