# georgiacivicdata

`georgiacivicdata` brings Georgia’s public data into R. It is the R
client for the API run by [Georgia Civic
Data](https://georgiacivicdata.org).

[Georgia Civic Data](https://georgiacivicdata.org) gathers, organizes,
and standardizes Georgia’s public data, helping residents, parents,
researchers, and professionals find answers in data that is already
theirs. We put every dataset in the same shape, with the same codes for
counties, school districts, schools and demographic groups. Datasets
from different agencies can be compared and joined due to the
standardization.

The data covers education, Census, health, and immigration. Geographic
detail spans from the whole state down to single schools and Census
tracts. Each dataset comes with a data contract that documents its
source, its columns, and the limits of the data.

With `georgiacivicdata` you can:

- Find Georgia datasets, read the documentation, and get rows in R.
- Get tibbles with consistent column types: codes stay text so leading
  zeros survive, years are integers, and rates are proportions between 0
  and 1.
- See every school, district, and county code with its name and filter
  by name instead of code.
- Get school attendance zones and district boundaries as ‘sf’ objects,
  ready to map.
- Look up the schools zoned for any Georgia address.

There is no API key and nothing to configure.

## Installation

Install the development version from GitHub:

``` r

# install.packages("pak")
pak::pak("shanejorr/georgia-data-rpackage")
```

## Example: Graduation rates in Fulton County

This walkthrough answers one question from start to finish: how has the
high school graduation rate in Fulton County Schools changed over time?
It follows the usual workflow:

- Find a dataset:
  [`gcd_search()`](https://georgiacivicdata.org/r/reference/gcd_search.md)
  or
  [`gcd_datasets()`](https://georgiacivicdata.org/r/reference/gcd_datasets.md).
- Learn what is in it:
  [`gcd_columns()`](https://georgiacivicdata.org/r/reference/gcd_columns.md)
  and
  [`gcd_describe()`](https://georgiacivicdata.org/r/reference/gcd_describe.md).
- Download the data:
  [`gcd_rows()`](https://georgiacivicdata.org/r/reference/gcd_rows.md).
- Plot them: any R plotting tool, such as ‘ggplot2’.

### Step 1: find the right dataset

Every dataset has a short name, such as `graduation_rate_4_year_cohort`,
and you need that name to get data. If you don’t know it,
[`gcd_search()`](https://georgiacivicdata.org/r/reference/gcd_search.md)
searches the catalog in plain words. It matches both keywords and
meaning so you don’t need the exact wording of a dataset’s title. Each
result has the dataset’s `name`, `title`, and the first and last years
it covers.

``` r

library(georgiacivicdata)

gcd_search("high school graduation", n = 5)[, c("name", "title", "year_min", "year_max")]
#> ℹ Lookup tables that match: "schools" and "districts". See `gcd_dimension()`.
#> # A tibble: 5 × 4
#>   name                          title                                    year_min year_max
#>   <chr>                         <chr>                                       <int>    <int>
#> 1 ccrpi_graduation_rate         High School Graduation Rates                 2012     2025
#> 2 graduation_rate_4_year_cohort Four-Year Cohort Graduation Rate             2004     2025
#> 3 high_school_completers        High School Completers                       2011     2025
#> 4 postsecondary_c11             Postsecondary Enrollment of HS Graduate…     2010     2023
#> 5 postsecondary_c12             Postsecondary Outcomes of HS Graduates …     2008     2021
```

The four-year cohort graduation rate, `graduation_rate_4_year_cohort`,
is the one we want: the share of students who graduate within four years
of starting ninth grade.
[`gcd_datasets()`](https://georgiacivicdata.org/r/reference/gcd_datasets.md)
lists the whole catalog, allowing browsing instead of searching.

### Step 2: learn what is in it

Check what datasets hold before downloading them.
[`gcd_columns()`](https://georgiacivicdata.org/r/reference/gcd_columns.md)
lists a dataset’s columns with its type, role (a year, a place, a
demographic group, or a measured value), and unit.

``` r

gcd_columns("graduation_rate_4_year_cohort")[, c("column", "type", "role", "unit")]
#> # A tibble: 7 × 4
#>   column          type    role           unit      
#>   <chr>           <chr>   <chr>          <chr>     
#> 1 year            integer year           <NA>      
#> 2 district_code   string  fk_district    <NA>      
#> 3 school_code     string  fk_school      <NA>      
#> 4 demographic     string  fk_demographic <NA>      
#> 5 num_graduates   integer metric         count     
#> 6 num_cohort      integer metric         count     
#> 7 graduation_rate number  metric         proportion
```

Each row is one year, one place and one demographic group. The value we
want is `graduation_rate`, a proportion on the 0-1 scale, so 0.9 means
90%.

[`gcd_describe()`](https://georgiacivicdata.org/r/reference/gcd_describe.md)
prints the rest of the dataset’s documentation, which includes its
source, the years and detail levels it covers, and notes on how to use
it. Those notes matter here. Georgia changed how it calculates the
graduation rate in 2011, so the rates before and after 2011 are not
comparable. We will start the series in 2011.

### Step 3: get the rows

[`gcd_rows()`](https://georgiacivicdata.org/r/reference/gcd_rows.md)
downloads a dataset’s rows as a tibble. Filters narrow the request:

- `district` takes a district’s name and turns it into the district code
  for you (`district_code` takes the code directly).
- `detail = "districts"` asks for district-wide figures rather than one
  row per school.
- `demographic` picks the student groups; `"all"` is every student.
- `year` picks the years.

``` r

grads <- gcd_rows(
  "graduation_rate_4_year_cohort",
  district = "Fulton County",
  detail = "districts",
  demographic = c("all", "black", "hispanic", "white"),
  year = 2011:2025
)
#> ℹ This result contains NULL metric cells, which mean the value was SUPPRESSED (small counts),
#>   not zero — do not report or chart a NULL as 0 (see null_semantics and each column's
#>   null_meaning).
#> ℹ Demographic groups overlap across categories and may overlap within a category (active_duty
#>   can be a subset of military_connected). Read the dataset's definitions and non_additive
#>   declarations. Use the published `all` total when available, never add it to its subgroups.
#>   Counts reconcile only for complete, disjoint groups; subgroup rates generally do not add to
#>   the overall rate.
#> ℹ `district_census_id` is a 5-digit Census school-district code, NOT a county FIPS, and a
#>   district is not 1:1 with a county — do not map these district rows as counties.
grads
#> # A tibble: 60 × 11
#>     year district_code district_name district_census_id district_type demographic
#>    <int> <chr>         <chr>         <chr>              <chr>         <chr>      
#>  1  2011 660           Fulton County 02280              standard      all        
#>  2  2011 660           Fulton County 02280              standard      black      
#>  3  2011 660           Fulton County 02280              standard      hispanic   
#>  4  2011 660           Fulton County 02280              standard      white      
#>  5  2012 660           Fulton County 02280              standard      all        
#>  6  2012 660           Fulton County 02280              standard      black      
#>  7  2012 660           Fulton County 02280              standard      hispanic   
#>  8  2012 660           Fulton County 02280              standard      white      
#>  9  2013 660           Fulton County 02280              standard      all        
#> 10  2013 660           Fulton County 02280              standard      black      
#> # ℹ 50 more rows
#> # ℹ 5 more variables: demographic_label <chr>, demographic_category <chr>,
#> #   num_graduates <int>, num_cohort <int>, graduation_rate <dbl>
```

Each place comes back with both its code and its name, and each
demographic code with a readable label. The API also prints advisories
as messages. Here they warn that the `all` total sits beside the
subgroups, so never add a total to its subgroups. A missing value (`NA`)
usually means the figure was **suppressed** to protect small groups, not
that it is zero.

### Step 4: plot the overall rate

The tibble works with any R tool. To plot the overall rate over time,
keep the rows where `demographic` is `"all"` and draw a line with
‘ggplot2’.

``` r

library(ggplot2)

grads_all <- grads[grads$demographic == "all", ]

ggplot(grads_all, aes(x = year, y = graduation_rate)) +
  geom_line(colour = "#1f5f8b", linewidth = 1) +
  geom_point(colour = "#1f5f8b", size = 2) +
  scale_y_continuous(labels = scales::label_percent(), limits = c(0.6, 1)) +
  labs(
    title = "Fulton County Schools four-year graduation rate, all students",
    x = NULL, y = "Graduation rate",
    caption = "Source: Georgia Civic Data (GOEWS)"
  ) +
  theme_minimal()
```

![Line chart of the Fulton County Schools four-year graduation rate for
all students, 2011 to 2025. The rate rises from about 70% in 2011 to
about 92% in 2025.](reference/figures/README-grad-plot-1.png)

## Lookup tables

Datasets hold codes and figures, with place names added. Everything else
known about a place lives in shared lookup tables, called dimensions: a
district’s type, a school’s level, grade span, locale (city, suburb,
town or rural), charter status, address and coordinates, and a Census
tract’s land area and population.
[`gcd_dimension()`](https://georgiacivicdata.org/r/reference/gcd_dimension.md)
returns one as a tibble, with the same name filters as
[`gcd_rows()`](https://georgiacivicdata.org/r/reference/gcd_rows.md).

Lookup tables help you:

- Browse what exists before you request data, such as every active high
  school in a district.
- Add attributes the datasets don’t carry, then filter or group by them.
- Map schools with their coordinates.

Here are the active high schools in Fulton County with their locale:

``` r

gcd_dimension("schools", district = "Fulton County", school_level = "high",
              active = TRUE,
              columns = c("district_code", "school_code", "school_name", "locale"))
#> # A tibble: 22 × 4
#>    district_code school_code school_name                      locale
#>    <chr>         <chr>       <chr>                            <chr> 
#>  1 660           0106        Milton High School               suburb
#>  2 660           0118        Hapeville Charter Career Academy suburb
#>  3 660           0119        Cambridge High School            suburb
#>  4 660           0176        Banneker High School             suburb
#>  5 660           0191        Roswell High School              city  
#>  6 660           0198        Centennial High School           city  
#>  7 660           0203        Northview High School            suburb
#>  8 660           0205        Alpharetta High School           city  
#>  9 660           0291        Creekside High School            suburb
#> 10 660           0386        Independence High School         city  
#> # ℹ 12 more rows
```

To compare graduation rates by locale, join the locale to school-level
graduation rates. School codes repeat across districts, so join on
`district_code` and `school_code` together.

``` r

schools <- gcd_dimension("schools", district = "Fulton County",
                         columns = c("district_code", "school_code", "locale"))

school_grads <- gcd_rows("graduation_rate_4_year_cohort",
                         district = "Fulton County", detail = "schools",
                         demographic = "all", year = 2025, quiet = TRUE)

school_grads <- merge(school_grads, schools, by = c("district_code", "school_code"))
aggregate(graduation_rate ~ locale, data = school_grads, FUN = median)
#>   locale graduation_rate
#> 1   city         0.95080
#> 2  rural         0.94330
#> 3 suburb         0.96585
```

Fulton County has only two rural high schools, so treat this as an
illustration, not a finding.

## School zones and places

[`gcd_school_zones()`](https://georgiacivicdata.org/r/reference/gcd_school_zones.md)
returns school attendance zones as an ‘sf’ object, ready to map. This
map shows the high school zones in Atlanta Public Schools:

``` r

zones <- gcd_school_zones(district = "Atlanta Public Schools", zone_level = "high")
ggplot(zones) +
  geom_sf(aes(fill = school_name), colour = "white", linewidth = 0.3) +
  labs(title = "Atlanta Public Schools high school zones, 2026-27", fill = NULL) +
  theme_void() +
  theme(legend.text = element_text(size = 7))
```

![Map of the Atlanta Public Schools high school attendance
zones.](reference/figures/README-zones-1.png)

[`gcd_locate()`](https://georgiacivicdata.org/r/reference/gcd_locate.md)
goes the other way: give it an address or a point, and it returns the
places that contain it, including the county, Census tract, school
district and zoned schools. Addresses are geocoded on your computer with
the U.S. Census geocoder, so only the point reaches the Georgia Civic
Data API.

``` r

# The Georgia State Capitol
gcd_locate(address = "206 Washington St SW, Atlanta, GA 30334")[
  , c("geographic_type", "geographic_id", "geographic_name", "grades")
]
#> ℹ A zone is the default assignment, not the only option: a Georgia student may attend another
#>   public school by transfer, or a charter, magnet or other choice school. See
