Text: three third-party datasets were used for this study. 2009 restricted data from national health interview survey (nhis) is publicly available dataset (available at http://www.cdc.gov/nchs/nhis/nhis_2009_data_release.htm), howver, the authors of this study requested a restricted nhis dataset (with geography variable) from the cdc research data center (rdc) which hosts the restricted data. due to ethical and legal reasons, the rdc does not make protected information (e.g., participantsí geography location) publically available. researchers can gain access to analyze the restricted data via an application to the rdc. interested researchers may submit an application to the rdc to gain remote access to analyze the data. a second dataset was derrived from the 2009 american nonsmokers' rights foundation (anrf) united states tobacco control database. for the anrf data, researchers can purchase a run of data from the database. the anr foundation (http://www.no-smoke.org/document.php?id=313) can be contacted at 510-841-3032 or by email at tobaccolawsdatabase@no-smoke.org. finally, census estimated population data is publicly available and archived at the ucscensus website. we used the sub est2009: subcounty resident population estimates: april 1, 2000 to july 1, 2009. file: 7/1/2009 subcounty estimates file.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
