As every year, Istat reviews the list of items included in the consumer price index basket, and updates as well the survey techniques and the weights of each item to compile inflation.
The 2019 basket for the Italian consumer price indices for the whole nation (NIC) and for blue and white-collar households (FOI) is made up of 1,507 elementary products (1,489 in 2018), which are grouped into 922 products and 407 product aggregates.
