jonathan.levy@chicago.gov — Mon, 19 Oct 2026 21:43:47 +0000

This dataset contains the revenue detail portion of the 2027 Budget Recommendations for Local funds. “Local” funds are all funds, other than grant funds, used by the City for non-capital operations - including, but not limited to, the Corporate Fund, Water Fund, Midway and O’Hare Airport funds, Vehicle Tax Fund, and the Library Fund.

Dataset Created: Budget - 2027 Budget Recommendations - Positions and Salaries

jonathan.levy@chicago.gov — Mon, 19 Oct 2026 21:41:54 +0000

This dataset includes recommended positions and salaries for 2027 by title (without names) and salary. The dataset is excerpted from the 2027 Budget Recommendations, which is the line-item budget proposed by the Mayor to the City Council for approval. Disclaimer: the “Total Budgeted Unit” column displays either A) the number of employees AND vacancies associated with a given position, or B) the number of budgeted units (ie. hours/months) for that position. “Position Control” determines whether Total Budgeted Units column will count employees and vacancies or hours/months. If a Position Control is 1, then employees and vacancies are displayed; if a Position Control is 0, then the total number of hours/months recorded is displayed. This dataset follows the format of the equivalent datasets from past years except that Division Code, Section Code, Subsection Code, and Position Control have changed from Number to Text (not all in the same year) in order to accommodate non-numeric values.

Dataset Created: SARS-CoV-2 Molecular Sequencing Results – Clinical Specimen and Wastewater Samples

maria.fiorillo@chicago.gov — Thu, 13 Aug 2026 19:26:03 +0000

The SARS-CoV-2 virus, or the virus that causes COVID-19, has mutated numerous times since it was first recognized in humans at the start of the COVID-19 pandemic. These mutations, if distinct enough, can result in new types of SARS-CoV-2, which are called different “lineages” of the virus. Depending on the types of genetic mutations involved, SARS-CoV-2 lineages can vary widely in their ability to cause severe disease, transmit between people, or escape the protective effects of vaccination. During high levels of COVID-19 in the community, multiple lineages of the virus can be circulating at once. In other words, different Chicagoans can both be sick with COVID-19, but due to infection with different lineages. For this reason, it is important to understand generally which lineages of SARS-CoV-2 are circulating in Chicago and infecting residents. With a better understanding of more or less prevalent lineages, the Chicago Department of Public Health (CDPH) can help advise healthcare providers and residents about the best ways to take protective action. This dataset includes genetic sequencing results from both clinical laboratory specimens and wastewater samples. Results from these datasets—and a description of each—are currently published in separate datasets: wastewater and laboratory. Briefly: - Wastewater samples are collected from across multiple city sites twice weekly year-round. These samples are tested for the concentration of SARS-CoV-2 virus and then are genetically sequencing to determine which virus lineages are present and in what relative amount. Because wastewater is always collected each week, genetic sequencing results for wastewater data are available weekly. - Clinical laboratory samples represent positive SARS-CoV-2 PCR tests voluntarily reported by network of several hospital laboratories in Chicago as well as two commercial laboratories serving Chicago facilities. These data do not include patient demographic nor geographic information and represent both Chicago and non-Chicago residents tested by the reporting facility. Because sample submission volume varies throughout the year and can be very low when community-levels of COVID-19 are low, genetic sequencing results are aggregated to the monthly level. For each set, the “lineage percent” is provided for all detected lineages, which reflects the relative amount of the lineage detected across all samples collected during that time period (as a percent of all lineages detected). Results for both datasets are aligned to the Saturday ending each week; because of the different aggregation timelines, results should be interpreted as follows: - Wastewater data reflect the relative proportion of all lineages detected that week in wastewater. - Clinical data reflect the relative proportion of all lineages detected over the past four weeks across all clinical samples.
