Estimating Small Area Income Deprivation: An Iterative Proportional Fitting Approach

Small area estimation and in particular the estimation of small area income deprivation has potential value in the development of new or alternative components of multiple deprivation indices. These new approaches enable the development of income distribution threshold based as opposed to benefit count based measures of income deprivation and so enable the alignment of regional and national measures such as the Households Below Average Income with small area measures. This paper briefly reviews a number of approaches to small area estimation before describing in some detail an iterative proportional fitting based spatial microsimulation approach. This approach is then applied to the estimation of small area HBAI rates at the small area level in Wales in 2003-5. The paper discusses the results of this approach, contrasts them with contemporary ‘official’ income deprivation measures for the same areas and describes a range of ways to assess the robustness of the results

Analysis of VP2 gene sequences of canine parvovirus isolates in India

The epidemiology of canine parvovirus (CPV) infections in dogs in India was examined using 27 isolates collected during a two-year period. The VP2 genes of 22 isolates were sequenced, and the deduced amino acid sequences were compared. The results indicated that the isolates belonged to CPV type 2a except four, which belonged to CPV type 2b. Comparison of the VP2 gene sequences revealed that the Indian isolates formed separate lineages distinct from the South East Asian isolates. The canine parvovirus isolates in India appear to evolve independently, and distinct geographical patterns of evolution could not be discerned in the isolates examined
