analysis: The text discusses the importance of careful decisions about data and information in agricultural planning, highlighting the need to consider both current and future needs. It reviews the data requirements of agricultural planners and the distinction between qualitative and quantitative planning procedures. The text also touches on the limitations of current agricultural statistics and the need for improvements in the production of socio-economic data and indicators related to the rural population. Given the focus on agricultural planning and data requirements, it is likely that the text is related to the field of agriculture.
