Data Table 2 columns: all n = 51 (28%), employees 22 (12%), customers 20 (11%), partners 9 (5%)

Fact [I] p095-02

Data Table 2 column headers give all attackers as n = 51 / 28%, current or former employees as n = 22 / 12%, customers, clients, patients, and visitors as n = 20 / 11%, and romantic partners and relatives as n = 9 / 5%.

Sample (n = 51 of undeterminable) · attackers in the NTAC 2023 population of 173 mass attacks

Why inferred table header: the column headers are printed in the table; the <br> marks the line break inside each printed header cell and is not printed text
