Statistical data, at a low aggregate level and with high frequency, is an essential tool for business decision makers. One example in this respect is monthly data on exports and imports in thousands of EUR, at county level, provided by the National Institute of Statistics Romania. This data is not offered in a seasonally adjusted form, although most of it exhibits seasonality. This paper proposes a simple and cost-free methodology to seasonally adjust these data, making it more suitable for business decision.
