Exploring Trends in Public Health Data
Time-series data is essential in government analysis because it provides a way to observe how key metrics change over time. In public health, time-series datasets often include yearly or monthly records of indicators like vaccination rates, disease incidence, or hospital admissions. By analyzing these trends, you can identify patterns, evaluate the effectiveness of interventions, and make informed policy decisions. For instance, tracking vaccination rates across several years helps public health officials determine whether outreach programs are increasing immunization coverage or if new strategies are needed to address stagnation.
12345678# List of dictionaries representing yearly vaccination rates for a region vaccination_data = [ {"year": 2018, "vaccination_rate": 72.5}, {"year": 2019, "vaccination_rate": 75.0}, {"year": 2020, "vaccination_rate": 78.3}, {"year": 2021, "vaccination_rate": 82.1}, {"year": 2022, "vaccination_rate": 85.6}, ]
To analyze trends, you need to compare values from one year to the next. Calculating year-over-year changes reveals how much a metric has increased or decreased. In public health, this approach helps you spot periods of rapid improvement or decline. For example, if vaccination rates rise each year, it suggests successful policy measures. If they fall or plateau, further investigation is needed. By computing the percentage change between years, you can standardize comparisons and more easily identify significant shifts in the data.
12345678# Calculate the percentage increase in vaccination rates from one year to the next for i in range(1, len(vaccination_data)): previous = vaccination_data[i - 1]["vaccination_rate"] current = vaccination_data[i]["vaccination_rate"] percent_change = ((current - previous) / previous) * 100 print( f"From {vaccination_data[i-1]['year']} to {vaccination_data[i]['year']}: {percent_change:.2f}% change" )
1. What is a time-series dataset, and why is it important in public health analysis?
2. How would you compute the change in a metric from one year to the next in Python?
3. What does a consistent increase in vaccination rates over several years suggest?
