The paper presents and discusses the age pattern of mortality observed in Ngayokheme (Sine Saloum, Senegal). It is compared to data of other developing areas and to model life tables. Mortality at ages 1 to 4 is shown to be much higher than anywhere else where data are available. Reasons for this pattern are investigated. Emphasis is given to the epidemiological pattern, especially to diarrheal...

Hashing is used extensively in hardware applications such as page tables for address translation. There is not much literature in this regard although hashing has been extensively studied for le organization. More speciically, there is no study of the practical performance of hashing functions used. In the literature we nd bit extraction and exclusive ORing hashing functions used, but there is ...

The practitioners of tabular data protection methods in national statistical agencies have some familiarity with commonly used table structures. However, they require some guidance on how to evaluate appropriateness of various sensitive tabular data methods when applied to their own table structure. With that in mind, we use a real life " typical " table structure of moderate hierarchical and l...

When it comes to product pricing and reserving, actuaries often need life tables that include a forecast of future longevity improvement. However, the production of such tables is not straightforward, because the demographic future of any human population is a result of complex and only partially understood mechanisms, and is highly uncertain. In recent years, actuaries have been understandably...

Despite its widespread use, the Coale–Demeny model life table system does not capture the extensive variation in age-specific mortality patterns observed in contemporary populations, particularly those of the countries of Eastern Europe and populations affected by HIV/AIDS. Although relational mortality models, such as the Brass logit system, can identify these variations, these models show sys...
