bookUnderstanding Public Sector Data Structures

Government analysts often work with structured data that describes populations, budgets, or services. Common formats include demographic tablesβ€”where each row represents a region with columns for population, income, or ageβ€”and budget allocations, which might list departments and their yearly funding. In Python, such tabular data is typically represented as a list of dictionaries. Each dictionary corresponds to a record (such as a region or department), with keys for each attribute and values for the corresponding data. This approach allows you to organize complex datasets in a way that is both readable and easy to manipulate.

# Representing a small population dataset as a list of dictionaries population_data = [ {"region": "North", "population": 120000, "median_income": 45000}, {"region": "South", "population": 95000, "median_income": 42000}, {"region": "East", "population": 110000, "median_income": 47000}, {"region": "West", "population": 105000, "median_income": 43000} ]

With your data organized as a list of dictionaries, you can easily access and manipulate information. For instance, to find all regions with a population above 100,000, you can filter the list by checking each dictionary's population value. If you want to calculate the average median income, you can loop through the list, extract each region's median_income, and compute the mean. This structure makes it straightforward to extract insights, generate summaries, or prepare data for visualization.

# Calculating the average median income across all regions total_income = 0 for record in population_data: total_income += record["median_income"] average_income = total_income / len(population_data) print("Average median income:", average_income)

1. Which Python data structure is best suited for representing a table of records where each record has named fields?

2. What is the advantage of using a list of dictionaries for government datasets?

3. How would you access the 'population' value for the first region in the dataset?
