In Indonesia, the Business Tendency Index (BTI) measures the expectations of entrepreneurs about current business income, production capacity, average working hours and future domestic and foreign orders, selling prices and raw materials. The survey covers a sample of around 2000 managers from large and medium companies from almost all regions of the country and from the main sectors of the economy (Agriculture, Mining and Quarrying, Manufacturing, Electricity, Gas and Water, Construction, Trade, Hotels, Transportation and Communication, Financial and Services). For each of the variables measured, the proportion of positive, negative and neutral answers is computed, and the final index is reported as a weighted average of those proportions. The BTI above 100 indicates an improving outlook and below 100 a deteriorating outlook.
