| Data on the organizational structure of the national economy are compiled from information kept in the Business Register (BR). The Business Register is established and administered by the Czech Statistical Office under Act No. 89/1995 Coll., on the State Statistical Service. It keeps records of businesses - legal persons and natural persons - that enjoy the status of entrepreneur. Every business that is economically active as shown by statistical surveys or administrative sources is considered a statistical enterprise-type unit (see Regulations No. 696/1993 and 2 186/1993). The Register is updated every month using data from company registers, trades licensing offices and statistical sources and is primarily used for designing and implementing statistical surveys. Business companies and partnerships include general commercial partnerships, limited liability companies, limited partnerships, partnerships limited by share (before 1993) and joint-stock companies. Cooperatives also include cooperative enterprises. Natural persons include private entrepreneurs who are in business in compliance with the Trades Licensing Act, self-employed farmers and natural persons carrying out other business activities governed by special regulations. Private entrepreneurs in total include private entrepreneurs running their businesses under the Trades Licensing Act and self-employed farmers. Private entrepreneurs in business under the Trades Licensing Act include natural persons having business permits according to Act No. 105/1990 Coll., on the Private Enterprise of Citizens (before 1992) or business licences (from 1992). Private entrepreneurs in business under other regulations (other than the Trades Licensing Act) include self-employed farmers, members of professional chambers and other natural persons whose business activities are regulated by separate regulations. Associations of natural persons, associations of legal persons include civic associations and legal organizational components thereof; political parties and movements and legal organizational components thereof; enterprises or economic establishments belonging to these associations or political parties (before 1993); churches and religious societies; professional associations; chambers and interest associations of legal persons. The reason underlying the considerable decrease in the number of units in 1994 is the completed re-registration of entrepreneurs in compliance with the Trades Licensing Act.
