Border surveys and Time Location Sampling (TLS): an application on incoming tourism in Sicily
2012
The increasing need of reliable and detailed information at a regional and subregional level poses some challenges related with the measurement of tourists flows, for tourism destination management, planning and promotion purposes,. The aim of this work is twofold; first, it intends to analyse and discuss the main features and limits of the official border surveys conducted in the majority of world’s countries, within the framework of Time Location Sampling (TLS) design; second, it suggests the implementation of TLS design at a subnational level, by presenting the sampling design of the survey on incoming tourists in Sicily, carried out between 2009-2010, aimed at estimating the unobserved …
The probabilities of selection of first and second stage units in the Time Location Sampling (TLS) design on incoming tourism in Sicily and Sardinia
2011
The present work aims to illustrate the criteria used for the determination of probabilities of selection of first and second stage units, given the available information, within the TLS design implemented for the survey of the Relevant National Interest Project (PRIN) on mobility of regional incoming tourism in Sicily and Sardinia. First and second stage units selection probabilities are necessary for the implementation of Hansen-Hurwitz class estimators for the estimation of the average number of stops made by tourists in Sicily, for the estimation of the share of un-observed tourism, and for the sampling errors associated.
