title: Washington Representatives Study (Organized Interests in Washington Politics) - 1981, 1991, 2001, 2006, 2011
title: Version 1

description: The Washington Representatives Study includes information about thousands of organizations involved in Washington D.C. politics, their organizational characteristics including the kinds of interests they represented and the nature of their membership, if any, and the activities they undertook in the pursuit of policy influence. This collection encompasses all organizations listed in the Washington Representatives directories (published by Columbia Books) for 1981, 1991, 2001, 2006, and 2011 as being active in national politics by virtue of either having an office in the D.C. area, or hiring D.C.-area consultants or counsel to represent them. These organizations have been classified into 96 categories based, principally, on the kinds of interests represented. Variables include organization name, membership category, founding year, and main objective, as well as number of lobbyists hired, number of amicus briefs filed, political action committee (PAC) donations made, and web-based lobbying activities.
description: The data are not weighted; however, the dataset contains six weight variables (WEIGHT, IN11WEIGHT, IN06WEIGHT, IN01WEIGHT, IN91WEIGHT, IN81WEIGHT) which users may wish to apply during analysis. An important part of the investigation was to place these political organizations into categories based on the nature of their functions, the interests represented, and, in many cases, their organizational structure. In contrast to most studies of organized interests that rely on highly aggregated categories, this study deliberately proliferated the number of categories in order to capture fine distinctions. In spite of the large number of categories, there were, inevitably, organizations that seemed to fit comfortably into more than one category. To accommodate such cases -- for example, the National Medical Association, Mothers against Drunk Driving, or the American Indian Higher Education Consortium -- the study permits an organization to be coded into as many as three categories. Thus, the NMA, a membership group of African-American physicians, was coded as both a professional association and an African-American organization. Organizations that were coded into two or three categories appear a corresponding number of times in the data. Thus, if an organization was coded as belonging to two categories, it appears twice in this data set, once for each category to which it was assigned. In order to correct for such multiple counting, it is necessary to apply weights. For additional information on weights, please refer to the Original P.I. Documentation in the ICPSR Codebook.
