Iowa Food Assistance Program Statistics by Month and County
data.iowa.gov | Last Updated 2018-11-28T23:01:40.000ZThe Food Assistance Program provides Electronic Benefit Transfer (EBT) cards that can be used to buy groceries at supermarkets, grocery stores and some Farmers Markets. This dataset provides data on the number of households, recipients and cash assistance provided through the Food Assistance Program participation in Iowa by month and county starting in January 2011 and updated monthly. Beginning January 2017, the method used to identify households is based on the following: 1. If one or more individuals receiving Food Assistance also receives FIP, the household is categorized as FA/FIP. 2. If no one receives FIP, but at least one individual also receives Medical Assistance, the household is categorized as FA/Medical Assistance. 3. If no one receives FIP or Medical Assistance, but at least one individual receives Healthy and Well Kids in Iowa or hawk-i benefits, the household is categorized as FA/hawk-i. 4. If no one receives FIP, Medical Assistance or hawk-i , the household is categorized as FA Only. Changes have also been made to reflect more accurate identification of individuals. The same categories from above are used in identifying an individual's circumstances. Previously, the household category was assigned to all individuals of the Food Assistance household, regardless of individual status. This change in how individuals are categorized provides a more accurate count of individual categories. Timing of when the report is run also changed starting January 2017. Reports were previously ran on the 1st, but changed to the 17th to better capture Food Assistance households that received benefits for the prior month. This may give the impression that caseloads have increased when in reality, under the previous approach, cases were missed.

Iowa Medicaid Payments & Recipients by Month and County
data.iowa.gov | Last Updated 2018-11-28T23:00:56.000ZThis dataset contains aggregate Medicaid payments, and counts for eligible recipients and recipients served by month and county in Iowa, starting with month ending 1/31/2011. Eligibility groups are a category of people who meet certain common eligibility requirements. Some Medicaid eligibility groups cover additional services, such as nursing facility care and care received in the home. Others have higher income and resource limits, charge a premium, only pay the Medicare premium or cover only expenses also paid by Medicare, or require the recipient to pay a specific dollar amount of their medical expenses. Eligible Medicaid recipients may be considered medically needy if their medical costs are so high that they use up most of their income. Those considered medically needy are responsible for paying some of their medical expenses. This is called meeting a spend down. Then Medicaid would start to pay for the rest. Think of the spend down like a deductible that people pay as part of a private insurance plan.

Iowa Child Welfare Assessments by Disposition, County and Year
data.iowa.gov | Last Updated 2018-04-23T18:58:17.000ZThis dataset provides the number and disposition of child welfare assessments conducted by the Department of Human Services beginning January 1, 2004. On January 1, 2014, the department began using the Differential Response System, which allows for a family assessment in additional to a traditional child abuse investigation for allegations of abuse and neglect. Data prior to 2014 only report child abuse investigations. The family assessment is not used in physical or sexual abuse cases, or other types of serious abuse cases seen. It is used only in denial of critical care cases where the child is not in imminent danger. If at any time during a family assessment it appears the child isn’t safe, the case is reassigned to the child abuse assessment pathway. The family assessment pathway results in pairing families with services and supports. The traditional child abuse assessments result in a finding. Findings include: “founded” meaning abuse occurred and results in perpetrator placement on the child abuse registry; “confirmed” meaning abuse occurred, but it was minor, isolated and not likely to reoccur, does not go on the central abuse registry; and “unconfirmed” meaning abuse did not occur.

The Geographic Names Information System contains information about physical and cultural geographic features of all types, current and historical, but not including roads and highways. The database assigns a unique, permanent feature identifier, the Feature ID, as a standard Federal key for accessing, integrating, or reconciling feature data from multiple data sets. The GNIS collects data from a broad program of partnerships with Federal, State, and local government agencies and other authorized contributors.
