  "instruction": "Using the 2014–2018 American Community Survey 5-year estimates, identify counties with limited internet access, a high share of seniors living alone, weak transportation conditions, and low income. Scope the analysis to North Carolina counties from this dataset and use the North Carolina statewide values from the same release as the comparison baseline. First, select counties with at least 4,000 households lacking internet access. Then, retain only counties that simultaneously meet all of the following conditions: share of households without internet access higher than the statewide share; share of households with a householder aged 65 or older living alone higher than the statewide share; share of households without a vehicle higher than the statewide share; and median household income lower than the statewide median. Finally, output all qualifying counties as a single line, sorted alphabetically by county name. Each county should be formatted as County|NoInternetHH|NoInternetRatePct|SeniorLivingAloneSharePct|NoVehicleRatePct|MedianIncome, with counties separated by commas. Percentage fields should be given to three decimal places without a percent sign.",
