Data for Manuscript Title "Hunting Militias at All Cost: Urban Military Operation and Birth Outcomes"

This dataset contains the replication files for the study "Hunting Militias at All Cost: Urban Military Operation and Birth Outcomes."

Research Description
This study hypothesizes that Operation Orion, a state-led military intervention in Medellín, Colombia, had unintended consequences on newborn health in the affected urban neighborhoods. Specifically, the study posits that exposure to the violence and stress generated by the operation during the first trimester of pregnancy could negatively impact birth outcomes. The study finds that infants exposed to Operation Orion in utero, particularly during their mothers' first trimester of pregnancy, experienced significant reductions in key health indicators: Birth weight decreased by an average of 116 grams, height at birth dropped by an average of 0.51 centimeters, and there was a 3% lower probability of having an APGAR score above 7.

Data Overview and Interpretation
The provided data was sourced from the Vital Statistics Reports (VSR) for Medellín, collected by the National Administrative Department of Statistics (DANE), covering the years 2000-2005. Data includes information on birth outcomes (e.g., birth weight, height, APGAR score) and relevant maternal characteristics such as marital status, education, and access to healthcare. The Vital Statistics Reports (VSR) provide administrative data that can be used to track and analyze health outcomes at birth. This study focused on the period between 2002 and 2003, aligning with the timeline of Operation Orion. The data includes detailed birth records, allowing the researchers to employ a Difference-in-Differences (DiD) methodology to isolate the causal effect of the operation by comparing birth outcomes in affected neighborhoods to unaffected areas before and after the intervention.
Stata .dta Files: The datasets provided in .dta format (Stata format) are ready to be used in any Stata-based analysis. Key variables such as birth weight, height, gestational length, and maternal characteristics are included, enabling replication of the analysis or further exploration of different aspects of the birth outcomes.
Do-Files: The folder contains Stata .do files that are pre-configured to replicate the tables and figures in the study.
Figures: Pre-generated figures and plots are available in .png and .pdf formats for visualizing the key results, such as the heterogeneous effects on birth outcomes and permutation test results.

本数据集包含研究《不惜一切代价清缴民兵：城市军事行动与新生儿结局》的复现文件。

研究概述
本研究提出假说：哥伦比亚麦德林市由国家主导的「猎户座行动」军事干预，会对受影响城区的新生儿健康产生非预期后果。具体而言，研究假设妊娠首三个月暴露于该行动引发的暴力与应激环境，将对新生儿结局产生负面影响。研究发现，宫内暴露于「猎户座行动」的婴儿，尤其是母亲妊娠首三个月暴露的婴儿，其关键健康指标出现显著下降：出生体重平均降低116克，出生身长平均减少0.51厘米，且APGAR评分高于7分的概率降低3%。

数据概览与解读
本次提供的数据来自哥伦比亚国家行政统计总局（National Administrative Department of Statistics, DANE）收集的《生命统计报告》（Vital Statistics Reports, VSR），覆盖2000年至2005年。数据包含新生儿结局相关信息（如出生体重、身长、APGAR评分）以及母亲的相关特征，例如婚姻状况、受教育程度与医疗可及性。《生命统计报告》（VSR）提供的行政数据可用于追踪与分析出生时的健康结局。本研究聚焦2002年至2003年这一时间段，与「猎户座行动」的时间线相契合。该数据集包含详细的出生记录，使得研究者可采用双重差分法（Difference-in-Differences, DiD），通过对比干预前后受影响城区与未受影响地区的新生儿结局，分离出该军事行动的因果效应。

Stata .dta格式文件
本次提供的.dta格式（Stata格式）数据集可直接用于任何基于Stata的分析。数据集包含出生体重、身长、妊娠时长以及母亲特征等关键变量，可用于复现本研究的分析流程，或进一步探索新生儿结局的不同维度。

Do文件
本文件夹包含预配置完成的Stata .do文件，可用于复现研究中的表格与图表。

图表文件
预生成的图表以.png和.pdf格式提供，用于可视化关键研究结果，例如新生儿结局的异质性影响与置换检验结果。
