Counting of people in official censuses and other social surveys produces representations that are arguably of far greater political importance than the representations produced by voting. The recent controversy around the use of sampling methods in US Census 2000 illustrates some important political-geographical dimensions of our decisions regarding whether and how to be counted in surveys. The argument is intended both to illuminate political features of this very important source of geographical data and to encourage a more self-consciously political engagement with the statisitical surveys through which modern citizens more or less consciously contribute to the shaping of our own lives.

Abstract We present a method to compare spatial interaction models against data based on well known statistical measures that are appropriate for such models and data. We illustrate our approach using a widely used example: commuting data, specifically from the US Census 2000. We find that the radiation model performs significantly worse than an appropriately chosen simple gravity model. Various conclusions are made regarding the development and use of spatial interaction models, including: that spatial interaction models fit badly to data in an absolute sense, that therefore the risk of over-fitting is small and adding additional fitted parameters improves the predictive power of models, and that appropriate choices of input data can improve model fit.

Liquor stores, or more colloquially “corner stores,” in Detroit, Chicago, NewYork, Los Angeles, New Orleans, Washington, and other major metropolitancities located in economically under-served, urban, majority-black neighborhoodshave been purchased by Arab American and Arab immigrants over thelast two decades. In order to understand the relationship of place to religionand race, I intend to examine the dynamics of the encounter between African-American Muslims and Arab and Arab-American Muslims (mostly Yemeni)at various liquor stores in Oakland, where, according to the US Census(2000), African Americans compose 64 percent of the population.Complicated by an ethno-religious component, Yemeni Muslim liquorstore ownership concentrated in Oakland’s highest density, crime-ridden,black-dominant, and economically poorest neighborhoods, although aidedby literature, requires a new theoretical arsenal for approaching the conflict.Little scholarly attention has been paid to the demographic shift in ownershipand the resulting relations between the two groups. This essay is by nomeans an attempt to provide a comprehensive portrait or a theoretical foundation.Better described as a pilot study, my participant observations during ...

Purpose This study provided reference data and examined psychometric properties for clausal density (CD; i.e., number of clauses per utterance) in children between ages 4 and 9 years from the database of the Edmonton Narrative Norms Instrument (ENNI). Method Participants in the ENNI database included 300 children with typical language (TL) and 77 children with language impairment (LI) between the ages of 4;0 (years;months) and 9;11. Narrative samples were collected using a story generation task, in which children were asked to tell stories based on six picture sequences. CD was computed from the narrative samples. The split-half reliability, concurrent criterion validity, and diagnostic accuracy were evaluated for CD by age. Results CD scores increased significantly between ages 4 and 9 years in children with TL and those with LI. Children with TL produced higher CD scores than those with LI at each age level. In addition, the correlation coefficients for the split-half reliability and concurrent criterion validity of CD scores were all significant at each age level, with the magnitude ranging from small to large. The diagnostic accuracy of CD scores, as revealed by sensitivity, specificity, and likelihood ratios, was poor. Conclusions The finding on diagnostic accuracy did not support the use of CD for identifying children with LI between ages 4 and 9 years. However, given the attested reliability and validity for CD, reference data of CD from the ENNI database can be used for evaluating children's difficulties with complex syntax and monitoring their change over time.
