Campus Safety Data Source Reference

Campus Safety and Security (CSS) — annual Clery Act crime and fire safety reporting for all Title IV postsecondary institutions. Full dataset covers primary offenses, VAWA offenses, hate crimes, arrests/referrals, and fire safety. Portal mirror provides only hate crimes data (2005-2021); primary offenses, VAWA, arrests, and fire safety require direct access to ope.ed.gov/campussafety. Use when analyzing campus hate crimes via Portal or understanding Clery Act reporting structure. Identified by IPEDS unitid.

Guide to understanding and using campus crime and fire safety data collected under the Clery Act.

> CRITICAL: Value Encoding

>

> The Education Data Portal mirrors use integer codes for categorical variables, not string labels:

>

> | Variable | Example Code | Meaning |

> |----------|--------------|---------|

> | bias | 1 | Race-based bias |

> | crime_type | 14 | Intimidation |

> | fips | 6 | California |

>

> See ./references/variable-definitions.md for complete code mappings.

> Truth Hierarchy: When interpreting variable values, apply this priority:

> 1. Actual data file (what you observe in the parquet/CSV) -- this IS the truth

> 2. Live codebook (.xls in mirror) -- authoritative documentation, may lag

> 3. This skill documentation -- convenient summary, may drift from codebook

>

> If this documentation contradicts the codebook, trust the codebook. If the codebook contradicts observed data, trust the data and investigate. Use get_codebook_url() from fetch-patterns.md to download codebooks.

What is Campus Safety and Security Data?

The Campus Safety and Security (CSS) data comes from the annual survey required by the Jeanne Clery Disclosure of Campus Security Policy and Campus Crime Statistics Act:

• Federal mandate: All Title IV institutions must report crime and fire statistics annually
• Consumer protection: Designed to inform students, parents, and employees about campus safety
• Primary source: U.S. Department of Education Office of Postsecondary Education
• Coverage: All postsecondary institutions receiving federal financial aid
• Reporting period: Calendar year (January 1 - December 31)
• Available years: 2005-2021 (hate crimes in Portal mirrors)
• Primary identifier: unitid (IPEDS institution ID, 6-digit integer)
• Official portal: https://ope.ed.gov/campussafety/
• Portal mirror coverage: Hate crimes only. For primary offenses, VAWA, arrests, and fire safety, access the Department of Education portal directly.

Hate Crime-Only Offenses

Codes 12-15 are only reported as hate crimes. They are not standalone Clery crimes unless bias-motivated.

Arrests and Disciplinary Referrals

| Category | What's Counted |

|----------|----------------|

| Liquor Law Violations | Arrests + Disciplinary referrals |

| Drug Law Violations | Arrests + Disciplinary referrals |

| Weapons Violations | Arrests + Disciplinary referrals |

Key Identifiers (Hate Crimes Dataset)

| ID | Format | Level | Example | Notes |

|----|--------|-------|---------|-------|

| unitid | 6-digit integer | Institution | 100654 | IPEDS institution ID |

| opeid | 8-character String | Institution | 00100200 | OPE institution ID (126 nulls in data) |

| inst_name | String | Institution | University of Alabama | Institution name |

| fips | Integer | State | 6 | State FIPS code |

> Note: The hate crimes dataset uses inst_name (not instnm). Columns like branch, address, city, zip, state, sector, enrollment are NOT present in the Portal mirror data. Join with IPEDS directory on unitid to obtain institutional characteristics.

Geographic Categories

| Location | Definition | Reported Separately? |

|----------|------------|---------------------|

| On-Campus | Buildings/property owned/controlled by institution, reasonably contiguous | Yes |

| On-Campus Student Housing | Residence halls (subset of on-campus) | Yes (as subset) |

| Noncampus | Institution-owned/controlled property not contiguous; student org properties | Yes |

| Public Property | Streets, sidewalks, parking within or immediately adjacent to campus | Yes |

Fire Safety Data

Fire data is reported only for on-campus student housing facilities:

| Data Element | Description |

|--------------|-------------|

| Number of fires | Total fires per building per year |

| Cause of fire | Intentional, unintentional, undetermined |

| Injuries | Fire-related injuries requiring treatment |

| Deaths | Fire-related fatalities |

| Property damage | Estimated dollar value |

| Fire safety systems | Sprinklers, alarms, smoke detectors, etc. |

Missing Data Codes

| Code | Meaning | When Used |

|------|---------|-----------|

| null | Missing/not reported | Data not submitted or not applicable (e.g., 352k null values in bias column) |

| 0 | Zero incidents | Explicitly reported as zero (distinct from missing) |

> Empirically verified: The hate crimes dataset in the Portal mirror does NOT use -1, -2, or -3 coded values. All missing data appears as null. This differs from some other Portal datasets (e.g., CCD) that use negative integer codes. Always verify against the actual data.

Data Access

Datasets for Campus Safety are available via the mirror system. See datasets-reference.md for canonical paths, mirrors.yaml for mirror configuration, and fetch-patterns.md for fetch code patterns.

| Dataset | Type | Years | Path | Codebook |

|---------|------|-------|------|----------|

| Hate Crimes | Single | 2005-2021 | csafety/colleges_csafety_hate_crimes | csafety/codebook_colleges_csafety_hate_crimes |

> CRITICAL: Limited Data in Portal Mirrors -- Only hate crimes data is available in the Portal mirrors (1 dataset). For other campus safety data (primary offenses, VAWA, arrests/referrals, fire safety), access the Department of Education directly at https://ope.ed.gov/campussafety/. Consult datasets-reference.md for the authoritative list of available mirror datasets.

Codebooks are .xls files co-located with data in all mirrors. Use get_codebook_url() from fetch-patterns.md to construct download URLs:

url = get_codebook_url("csafety/codebook_colleges_csafety_hate_crimes")

Fetching Data

Use the fetch_from_mirrors() pattern from fetch-patterns.md:

import polars as pl

# Fetch hate crimes data (all years, single-file dataset)
df = fetch_from_mirrors("csafety/colleges_csafety_hate_crimes")

# Filter by year
df_2021 = df.filter(pl.col("year") == 2021)

# Filter by bias category (1 = Race)
race_crimes = df.filter(pl.col("bias") == 1)

# Filter by crime type (14 = Intimidation)
intimidation = df.filter(pl.col("crime_type") == 14)

# Filter by institution
institution = df.filter(pl.col("unitid") == 100654)

# Filter by state FIPS code (6 = California)
california = df.filter(pl.col("fips") == 6)

• Bulk download: Available through Campus Safety website
• Custom reports: Generate by institution, state, or sector

Common Pitfalls

| Pitfall | Issue | Solution |

|---------|-------|----------|

| Using string codes | Portal uses integer codes for bias, crime_type, etc. | Always map integers via ./references/variable-definitions.md |

| Ranking schools by crime counts | Higher numbers may indicate better reporting, not worse safety | Normalize by enrollment; note reporting culture differences in ./references/limitations.md |

| Comparing across years naively | Crime definitions changed over time (especially sex offenses in 2014, VAWA added 2013) | Restrict comparisons to consistent-definition periods; document breaks |

| Treating zero as missing | Zero means explicitly reported zero incidents; missing means not reported | Check for null (missing) vs 0 (zero incidents) before analysis |

| Comparing CSS to FBI UCR data | Different definitions, scope, and reporting requirements | Never equate CSS and FBI statistics; see ./references/limitations.md |

| Assuming all crime data in mirror | Mirror only has hate crimes | Use Department of Education portal for primary offenses, VAWA, arrests, fire safety |

| Using instnm as column name | Hate crimes data uses inst_name, not instnm (which is the IPEDS convention) | Check actual column names with df.columns |

| Expecting -1/-2 missing codes | Hate crimes data uses null for missing, not negative integer codes | Check for nulls with pl.col("bias").is_null(), not pl.col("bias") == -1 |

| Ignoring multi-campus institutions | Branch campuses report separately; aggregating incorrectly inflates/deflates | Use branch field to distinguish campuses; see ./references/campus-geography.md |

| Ignoring underreporting | Many crimes go unreported; CSS captures only reported incidents | Acknowledge underreporting as a limitation in all analyses |

Reporting Timeline

| Date | Action |
