Juxtastat is the daily quiz from Urban Stats, the data site by Luke Brody and Kavi Gupta. Each of its five questions names two places and one statistic, for instance which of St. Lucie County, Florida, and Mecklenburg County, North Carolina, has a larger share of people with at least an undergraduate degree, and you tap the place you think ranks higher. The questions grow harder as you go, and signing in with Google keeps your history in step across devices. It quietly tests which of your hunches about places hold up.
Up front are two-way comparisons of places, starting with a U.S. population matchup, then games that rank or pick countries by a stated statistic, and finally map puzzles where you work out which statistic is being shown, for anyone more drawn to the data than the duel.
The nearest match in shape: five head-to-head picks a day between two American places, decided by which has the bigger population, and an endless supply of extra pairs from every state once those are done.
Juxtastat's love of regional data at a larger scale: each day picks one statistic and asks which state or region in the Americas comes out on top or bottom, which hits a value exactly, or which is the outlier.
Keeps the two-way choice but widens the subjects: twenty-five quick calls on which of two things is higher, split into five rounds, where country populations share space with movie ratings, search volume and music streams.
Ranks nations on one statistic per round, asking for the country at the top or bottom, the odd one out in a group, or a precise value, a world-level counterpart to Juxtastat's county questions.
Turns comparison into an assignment puzzle: you match eight countries to eight measures, such as life expectancy or passport strength, placing each where its global ranking is strongest, the kind of judgment Juxtastat trains.
Ranking by a single statistic, applied to food: you find which nation eats the most of one item per person, such as tangerines, and every miss shows where that guess sits among 143 countries.
Presents the data as a line chart: a hidden country's figures over time, for example a farm product's output, sit in red, and each country you name adds its own line for comparison, with five guesses.
Flips Juxtastat's question around: the map is already colored by some statistic, and you must say which one, with each guess drawing its own map for comparison and fresh clues arriving whenever you miss.
Asks the same reverse question in four rounds: what measure is a world heatmap displaying, read from its colors alone, with a once-a-week survival challenge on five lives for longer sessions.
A statistics map with a lie in it: one country shows a false value, and you have six accusations to find it, with honest countries cleared after each miss, which rewards knowing roughly how places compare.
Stays with American data of the kind Juxtastat quizzes on: a hidden state is found by comparing your guesses with it on things like census division, population and neighboring states, so knowing the map pays off.
Juxtastat is part of Urban Stats, a data site credited to Luke Brody and Kavi Gupta, which is why its questions draw on detailed regional statistics such as education levels for U.S. counties. Signing in through Google keeps the quiz history on every device, or you can export and import it by hand.
TerraeQuest asks for the nation at the head or foot of a ranking. For a food angle, Eatlas ranks 143 countries on how much of one item each eats per person.
Statameleon, HeatMapQuest and World Imposter all color a world map by a real statistic. In Statameleon and HeatMapQuest you work out which statistic is shown, while World Imposter plants a fake figure on one country, which you have six guesses to expose.
