Employee Payroll - Fiscal Year 2017 Quarter 2

Employee payroll data for all Cook County employees excluding Forest Preserves, indicating amount of base salary paid to an employee during the County fiscal quarter. Salaries are paid to employees on a bi-weekly basis.
Any pay period that extended between quarters will be reported to the quarter of the Pay Period End Date. (e.g. If a Pay Period runs 02/21-03/05, that pay period would be reported in the Q2 period, as the end of the pay period falls in March - Q2)

The county fiscal quarters are:
Q1: December - February
Q2: March - May
Q3: June - August
Q4: September - November

The Employee Unique Identifier field is a unique number assigned to each employee for the purpose of this data set, that is not their internal employee ID number, and allows an employee to be identified in the data set over time, in case of a name change or other change. This number will be consistent within the data set, but we reserve the right to regenerate this number over time across the data set.

本数据集收录了库克县所有雇员的薪资支付数据，不包括森林保护区雇员，具体指明雇员在县财政季度内所获得的基准薪资数额。薪资以双周支付给雇员。任何跨越季度的支付周期将归入支付周期结束日期所属的季度报告。（例如，若支付周期为02/21-03/05，则该支付周期将被计入第二季度，因为支付周期的结束日期位于三月，即第二季度。）

县财政季度划分如下：
Q1：十二月 - 二月
Q2：三月 - 五月
Q3：六月 - 八月
Q4：九月 - 十一月

雇员唯一标识字段是为本数据集分配给每位雇员的唯一编号，该编号并非其内部员工ID，用于在数据集中长期识别雇员，即便出现姓名变更或其他变更。该编号在数据集中将保持一致，但本方保留在数据集跨时间范围内重新生成该编号的权利。
