- For the tongue-in-cheek "law" about controversy, see Benford's law of controversy.
Benford's law, also called the first-digit law, states that in lists of numbers from many (but not all) real-life sources of data, the leading digit 1 occurs much more often than the others (about 30% of the time). Furthermore, the larger the digit, the less likely it is to occur as the leading digit of a number.
This applies to figures related to the natural world or of social significance - electricity bills, newspaper articles, street addresses, stock prices, population numbers, death rates, areas or lengths of rivers, physical and mathematical constants, and processes described by power laws (which are very common in nature).

Benford's Law - The audit technology is now known as Digital Analysis (DA). It tests for abnormalities in the digit patterns and abnormal number duplication in corporate data.
Benford's Law and Zipf's Law. - With the view to the eerie but uniform distribution of digits of randomly selected numbers, it comes as a great surprise that, if the numbers under investigation are not entirely random but somehow socially or naturally related, the distribution of the first digit is not uniform.
BenfordWiz - Software which produces and analyses Benford Sets. Hexagonal and Octagonal numbers are also included in the data sets.
Following Benford's Law, or Looking Out for No.1 - Dr.Theodore P. Hill asks his mathematics students at the Georgia Institute of Technology to go home and either flip a coin 200 times and record the results, or merely pretend to flip a coin and fake 200 results.
