Public Intelligence Console

Metric Explorer

Deterministic, reproducible metrics derived from directly observed source data. Every metric is labelled DERIVED and links to its formula, source fields, methodology and calculation audit. No predictions. No causation. No private intelligence scoring.

Methodology Audit trail Source lineage

concentration

EGM concentration index (HHI on EGM count)

concentration_index · v1 · LGA, STATE

HHI = sum( (venue_egm / total_egm_in_universe)^2 ) * 10000, universe = LGA × stream × period and NSW × stream × period

density

Machine density per 1,000 adults

machine_density_per_1000_adults · v1 · LGA

(sum(egm_count_at_period_end where lga = LGA) / lga_adult_population) * 1000

Venue density per LGA

venue_density_per_lga · v1 · LGA, STREAM

count(canonical_venues where current_lga = LGA AND venue_stream = STREAM)

financial

LGA net profit (AUD)

lga_net_profit_aud · v5.1 · LGA, STREAM, PERIOD

Direct observed value from NSW LGA quarterly/bi-annual gaming-machine reports.

LGA share of state-wide profit

lga_share_of_state_profit · v5.1 · LGA, STREAM, PERIOD

lga_net_profit_aud / SUM(lga_net_profit_aud across all observed LGAs in the same reporting period)

LGA tax paid (AUD)

lga_tax_paid_aud · v5.1 · LGA, STREAM, PERIOD

Direct observed value from NSW LGA quarterly/bi-annual gaming-machine reports.

Net profit per adult (LGA)

Profit per gaming machine

profit_per_machine · v5.1 · LGA, STREAM, PERIOD

lga_net_profit_aud / egm_count

Tax paid per gaming machine

tax_per_machine · v5.1 · LGA, STREAM, PERIOD

lga_tax_paid_aud / egm_count

Venue share of LGA net profit

venue_share_of_lga_profit · v1 · CANONICAL_VENUE

percentile_rank_state · v1 · CANONICAL_VENUE

percentile_rank(venue.egm_at_period | universe = NSW × stream × period)

temporal

3-year change (EGM count)

3_year_change · v1 · CANONICAL_VENUE, LGA

egm_at(latest_period) - egm_at(closest_observed_period ≈ latest_period - 36 months)

5-year change (EGM count)

5_year_change · v1 · CANONICAL_VENUE, LGA

egm_at(latest_period) - egm_at(closest_observed_period ≈ latest_period - 60 months)

Quarter-on-quarter change (EGM count)

quarter_on_quarter_change · v1 · CANONICAL_VENUE, LGA

(egm_latest - egm_previous_observed_period) where periods are adjacent observed periods

4-period rolling average (EGM count)

rolling_4_period_average · v1 · CANONICAL_VENUE, LGA

mean(egm_count_at_period_end over the four most recent observed periods for ENTITY)

Volatility band (CV across observed periods)

volatility_band · v1 · CANONICAL_VENUE, LGA

coefficient_of_variation(egm_count_series_observed) = stddev / mean, classified into LOW (<5%), MODERATE (5–10%), ELEVATED (10–20%), HIGH (>20%)

Year-on-year change (EGM count)

year_on_year_change · v1 · CANONICAL_VENUE, LGA

egm_at(latest_period) - egm_at(closest_observed_period ≈ latest_period - 12 months)
