Methodology

Gospel Shift: which way each neighborhood moved between 2020 and 2024

The map-layer name for the Gospel Impact Metric. One measurement, two labels, always the same number.

Turn it on in the explorer to see, tract by tract, where conditions opened, held or hardened, and how your neighborhood ranks against the country.

Definition

What is Gospel Shift?

Gospel Shift is the GospelGraph map layer that shows how far each U.S. census tract’s Shalom composite moved between two eras: the 2024 composite minus the comparable 2020 composite. Positive values mean conditions are opening, negative values mean they are hardening, and values from −0.7 to +0.8 mean the place is holding. It is the same quantity as the Gospel Impact Metric (GIM): Gospel Shift is the name on the map, GIM is the name of the metric, and the two always report the same number for the same tract.

The composite is Shalom v2, scored across five domains: Provision & Work, Justice & Protection, Life & Health, Household & Generations, and Social Fabric. Gospel Shift does not read church locations or Gospel access. It reads movement in the conditions of community life.

On the map

How does the map color Gospel Shift?

The layer paints every scored tract into one of five bands. The band edges are anchored to the measured national distribution of the 2020–2024 change and are shared with the GIM readout, so a tract cannot say "opening" in its panel and sit in a hardening color on the tile.

Because the edges sit at fixed positions in the national line-up, the shares are fixed as well. Roughly 30% of tracts will always fall in the bottom band and 10% in the middle one, whatever happened on the ground. That makes the colors a ranking, not a census of how the country fared.

  • Opening fast: +4.3 or more, the top fifth of tracts.
  • Opening: above +0.8 and below +4.3, the next fifth.
  • Holding: −0.7 to +0.8, the middle tenth.
  • Hardening: above −3.8 and below −0.7, the next fifth.
  • Hardening fast: −3.8 or less, the bottom 30%.
  • Insufficient sample: tracts below the publication-safe base. They get no color band and no change value. The current map build reports 83,072 tracts with a publication-safe change and 1,342 marked insufficient sample, of 84,414 in all.
Reading it

Is a hardening tract getting worse?

Not necessarily. "Hardening" means a tract moved worse than most other tracts did between the two readings. By itself it does not mean the place got worse. The whole national line-up sits left of zero, and part of that is the survey rather than the country: the 2016–2020 Census release that serves as the base was collected through the first year of the pandemic and sits about two points high. Subtract from an inflated base and everything tilts negative. A tract reading −0.5 is not "slightly bad"; it is doing better than half the country.

Survey error matters too. For an ordinary neighborhood the four-year change is known to within about seven points either way, nineteen times in twenty, while the holding band is one and a half points wide. So a single tract’s band is a fair place to start a conversation and a poor place to end one. Small shifts deserve careful, comparative reading alongside what you know locally.

Use

How should a church use the Gospel Shift layer?

Direction changes strategy because timing matters. A stable, heavily pressed tract may call for patient, embedded presence. A tract hardening fast may call for earlier care, before the strain shows on the street. An opening tract may be ready for partnership, planting or renewed outreach, and it is worth asking who is already at work there.

Use Gospel Shift to compare neighborhoods as they stand today: the line-up is fair, and a gap of several points between two tracts is telling you something. When your question is which way a place has been going over years, use the long-baseline view, GIM v3, which fits twelve overlapping survey windows and carries about a third of the noise. Where it cannot establish a direction, it says so. And when a decision will cost people years, use neither one on its own. Go and stand on the street.

Read Gospel Shift together with need pressure, the standing level, and the Gospel Desert Index, the structural access gap. A hard place that is climbing the line-up and a comfortable one sliding down it look the same on a standing score and call for different responses. The desert moved to the growth edge asks where the ground is opening fastest and who is hardening beside a church that is already there, and State of the Field reads the direction of travel nationally.

Not to be confused with

How is Gospel Shift different from GDI trajectory?

GospelGraph also keeps a separate historical read called GDI trajectory, which summarizes how the Gospel Desert Index moved across its 2015, 2017, 2019 and 2021 vintages. That is movement in structural Gospel access. Gospel Shift is movement in Shalom. The two answer different questions and are never substituted for one another.

Nor is Gospel Shift a measure of revival, decline or conversion, and a rising value does not prove any ministry caused it. Policy, markets, migration and investment move these numbers too. The full methodology explains each layer and what it cannot say.

Questions

Common questions

Is Gospel Shift the same as the Gospel Impact Metric?

Yes. Gospel Shift is the map-layer name for GIM. Both are the 2024 Shalom composite minus the 2020 composite, and they always report the same number for the same tract.

What is the Gospel Shift baseline?

The comparable 2020 Shalom composite. Gospel Shift subtracts it from the 2024 composite, so positive means opening and negative means hardening.

Does a hardening tract mean the neighborhood got worse?

Not by itself. The bands are positions in a national line-up, so hardening means a tract moved worse than most others did. The 2020 base also sits about two points high because of pandemic-era collection, which tilts every tract negative.

Why do some tracts have no Gospel Shift value?

Tracts below the publication-safe base are marked insufficient sample rather than given a change. The current map build marks 1,342 of 84,414 tracts that way.
