Historical lines are published counts. Dashed lines are derived: a least-squares trend through the last decade, extended as a FORECAST with its 80% range. Momentum, not a guarantee.

Restaurants by year, with trend and projection

ZIP Code Business Patterns, USPS ZIP 70431. Projection: linear trend v1, fitted 2006–2016, -0.1 restaurants per year, r² 0.43, confidence Medium.

Growth index (first year on file = 100)

Each category relative to its own first published count. Full/limited split is unavailable under SIC (before 1998).

Mix of the food-service market

Share of all food-service establishments. "Other" = snack bars, caterers, contractors, mobile.

Population and restaurants per 10,000 residents

Population points: 2010 Census count and ACS 5-year estimates on file (more vintages load over time). Density uses the population point within two years of each restaurant count. Population projection appears once three or more ACS years are loaded.

Restaurant growth vs. Louisiana and U.S. averages

Averages are the mean growth across all ZCTAs with the figure (state n = 362, U.S. n = 24,852). DERIVED from ZIP Code Business Patterns.

Why these scores?

Each score is a weighted average of national percentile ranks (0 = lowest of all ZCTAs with that figure, 100 = highest). Weights are set in the model registry, not in code, and every score carries its model version.

Market Momentum Score: 22 (High confidence)

Component	Value	Rank	Weight	Adds
5-year restaurant growth	0	42	50%	+20.9
10-year restaurant growth	-66.7	1	30%	+0.4
20-year restaurant growth	-50	4	20%	+0.9

Restaurant-count growth only until population and income growth series exist.

A high score is a statistical position among all U.S. ZCTAs, not a prediction that a restaurant will succeed.
