The transaction data is over a period of 14 months, running from the start of July 2021 to the end of August 2022. There are 5144 customers and 46926 unique accounts, with some customers having more than one account. The number of transactions per customer range from 1 to just over 2 000 for the 14-month period.

The train set contains 3600 customers along with their declared net income and the test data contains the remaining 1544 customers with the declared income excluded.

Along with the train and test files is the transaction history for each customer which details the various transactions each customer engaged in over the entire period of recording. There are also data files containing demographic information on each customer as well as files describing some of the categorical variables related to the customers.
