Bongaarts Proximate Determinant Index Calculator Multiply the Bongaarts proximate determinant indices for marriage, contraception, abortion, and postpartum infecundability.
Bongaarts Tempo-Adjusted TFR Calculator Apply the Bongaarts-Feeney tempo adjustment to recover the period fertility rate free of postponement distortion.
Cause-Deleted Life Expectancy Gain Calculator Report the life expectancy gained when a competing cause of death is deleted from the life table.
Clark Urban Density Gradient Calculator Fit the negative exponential of Clark's urban density model between two ring measurements.
Class Reproduction Odds Ratio Calculator Quantify class inheritance with the odds ratio comparing top-origin sons staying on top against bottom-origin sons rising.
Duncan SEI Socioeconomic Index Calculator Apply Duncan's 1961 regression to an occupation's high-income and high-school-graduate percentages to estimate its historical socioeconomic index score.
EU Severe Material Deprivation Rate Calculator Compute the EU severe material deprivation rate from the deprived count and surveyed population.
Four-City Primacy Index Calculator Score urban primacy as the largest city's population over the combined next three cities.
Gibrat Growth Law Checker Test Gibrat's law of proportional growth by comparing average growth rates of large and small units against a tolerance.
Glass Social Fluidity Index Calculator Compute the cross-product association odds ratio for a two-by-two mobility table; larger values indicate stronger class persistence and therefore less social fluidity.
Gross Migration Stream Total Calculator Sum every off-diagonal origin-destination cell of a square migration stream table into gross migration, excluding non-movers on the diagonal.
Hollingshead ABI Status Index Calculator Compute the Hollingshead Two Factor Index of social position as occupation times seven plus education times four.
House Price-to-Income Affordability Ratio Divide the median home price by median household income and flag ratios above the classic three-times affordability line.
Life Table e(x) From l(x) Step Calculator Advance one life table step: form person-years lived from adjacent survivorships and divide by them plus the remaining tail for life expectancy.
Mean Age at Childbearing Calculator Weight the age schedule of fertility by births to obtain the mean age at childbearing.
Migration Age Propensity Schedule Calculator Build the age-specific migration propensity schedule from migrant counts and the population at risk.
Migration Effectiveness Index Calculator Measure what share of gross migration actually changes the population with the migration effectiveness index.
Mobility Transition Probability Table Tool Row-normalize an origin-by-destination flow count table into mobility transition probabilities.
Net Migration Census Survival Method Calculator Isolate net migration as the census count minus the survivors projected forward from the earlier census.
Overcrowded Dwelling Rate Eurostat Calculator Compute Eurostat's overcrowding rate as the percentage of people living in households classified as overcrowded.
Parity Progression Ratio Calculator Convert counts of women at each birth parity into the parity progression ratios between them.
Postponement Proportion Index Calculator Measure the share of births born to mothers at or above a chosen postponement reference age.
q(x) Probability of Death From m(x) Calculator Convert a central death rate into the life table probability of dying over the age interval.
Ravenstein Gravity Flow Index Calculator Rank migration potential between two places with the gravity model product of populations over squared distance.
Rent Burden 30% Checker Flag rent-burdened households spending at least thirty percent of gross income on rent.
Replacement-Level Fertility Checker Check a total fertility rate against the conventional 2.1-birth benchmark used for low-mortality populations; the actual replacement rate varies with mortality and sex ratio at birth.
Robin Hood (Pietra) Index Calculator Compute the Robin Hood (Pietra) inequality index as the total absolute deviation of incomes from the mean divided by twice the aggregate income.
S80/S20 Ratio Calculator Report the S80/S20 income ratio between the mean of the richest twenty percent and the poorest twenty percent.
Schutz Index Calculator Compute the Schutz inequality index as the below-mean income shortfall divided by total income.
Spouse Status Gap Difference Calculator Measure the absolute occupational prestige gap between spouses in a household.
Status Inconsistency Score Calculator Score status inconsistency as the spread across education, income, and occupational prestige rank percentiles.
Stouffer Intervening Opportunities Access Ratio Calculator Compute an access-ratio heuristic as opportunities at a destination divided by opportunities encountered before it; this is not the cumulative Stouffer formulation for migration probability.
Survival Ratio Census Method Calculator Compare a birth cohort across two censuses to estimate its five-year survival ratio.
Top 10% Income Share Calculator Compute the share of total income held by the richest decile or any chosen top fraction of a sample.
Treiman Occupational Prestige Score Lookup Look up approximate Treiman SIOPS occupational prestige scores for a small set of common occupations.
Wealth Quintile Ratio Calculator Divide a wealth sample into fifths and report the ratio of the richest fifth's average to the poorest fifth's.
Zahavi Commute Time Budget Constant Checker Multiply a mean one-way commute time by commute trips per day and compare this commute-only proxy with Zahavi's approximate one-hour all-travel daily budget.
Zipf Rank-Size Exponent Checker Test a city against the Zipf rank-size rule and report how far its population deviates in percent.
