   What is the causal effect of a one-unit increase in log(number of broadband providers) on affective partisan polarization (outcome scaled 0-1), estimated for compliers using county-level data pooled across 2004 and 2008?

   | Variable Name | Description | |--------------------|-----------------------------------------------------------------------------| | (unnamed) | Row identifier / dataset index (row number) | | D | Log of the number of broadband providers in the county (natural log of provider count from FCC records) | | outcome | Rescaled measure of partisan affect: difference in feeling‑thermometer scores toward the in‑ and out‑party presidential candidates (scaled 0–1) | | Total_log | Log of the state right‑of‑way (ROW) regulation index (Beyer & Kende 2003) | | region | Census region categorical label (e.g., "1: Northeast", "2: Midwest", "3: South", "4: West") | | percent_black | Proportion of the county population identifying as Black (fraction between 0 and 1) | | percent_white | Proportion of the county population identifying as White (fraction between 0 and 1) | | percent_male | Proportion of the county population that is male (fraction between 0 and 1) | | lowed | Indicator for low‑education county status (e.g., "0: Not low‑education type") | | unemploymentrate | County unemployment rate (percent) | | density | County population density (as provided in the ICPSR County Characteristics file) | | HHINC_log | Log of median household income in the county (natural log of HH income) | | year | Survey year (2004 or 2008) | | state | U.S. state name (state of residence / county mapping) | Data Description: This merged file brings together individual survey records from national rolling‑cross‑section studies (NAES 2004 and 2008) with county‑level socioeconomic indicators (ICPSR County Characteristics), broadband provider counts (FCC Form 477), and a state‑level right‑of‑way (ROW) regulation index (Beyer & Kende 2003). Each row represents a respondent observation linked to county and state characteristics for the survey year; variables include a constructed index of partisan affect, log‑transformed measures of broadband/provider and income, regional codes, and standard county demographic and economic controls. The data were assembled to enable descriptive and comparative analyses of regional policy indicators, local broadband availability, and survey‑measured attitudes.
